Will she or won't she?!? Many were convinced Adele's follow-up to her blockbuster 21 album was coming last year, when the powerhouse tweeted "bye bye 25... See you again later in the year "—but we never got a 25, nor any other new Adele music. This year looks like a good bet with producers like Ryan Tedder (who helmed 21 single "Rumour Has It") giving out more and more details. Can Adele break even more sales records with this album? We don't care...we just want her back!!! — Jeff Benjamin

While Britney herself has yet to say anything, Iggy Azalea let the cat out of the bag after revealing she laid down a verse for the pop star's first single from her upcoming album. After the disappointing performance (for pop princess standards) of 2013's Britney Jean, we have a feeling the new Las Vegas resident is really ready to work...bitch! — Jeff Benjamin

Unlike some pop stars, Christina Aguilera doesn’t Tweet often, so when she does, it’s usually a big deal. In April 2014, after announcing her pregnancy, @Xtina tweeted, “So blissful in taking this time for creating all things blossoming new on the horizon…album, baby & beautiful music to come.” In October, two months after her daughter Summer Rain was born and after it was announced Aguilera would be returning to The Voice in 2015, she tweeted, “New baby. New Music. New season of @NBCtheVoice. Bringing #FireAndFun to all, can’t wait for 2015!” The biggest tease yet? In early November Xtina posted a photo of herself in a studio recording, with Pharrell’s signature hat sitting on the control board, confirming the two weren’t just co-stars on the upcoming season of The Voice, but also working together on new music! Legendary hip hop producer DJ Premier has confirmed his involvement as well, and production duo Da Internz are also attached to the project. (They've even gone so far as to describe Christina's new stuff as "caviar ratchet.") Considering the talent involved, we’re expecting (and hoping for) a more R&B/soul album from Xtina. With the new season of The Voice premiering February 23, new music may be closer than we think! — Mark Sundstrom

After leading 2NE1 to global stardom, CL will step out on her own with a full-fledged solo debut in America. She's got an all-star cast helping her from management (Justin Bieber and Ariana Grande manager Scooter Braun) to producers (she's been in the studio with Diplo, Skrillex and Blood Diamonds) to friends (designer du jour Jeremy Scott regularly dresses her; she once brought Rita Ora onstage for a performance). With her powerful combo of rapping and singing, CL could be the fresh new pop star of the year and very well make for the most successful Asian musician...ever? — Jeff Benjamin

2015 might be Drake's year. The "Hold On, We're Going Home" rapper is headlining Coachella and New York City's Governors Ball this year, so perhaps a new album is underway? We're banking on it after his killer verse in Nicki Minaj's "Only," and his fierce collabo with Future, "Never Satisfied." Then, of course, there were the three tracks Drake surprise-dropped on his Soundcloud. Come on, Drizzy! We are ready! — Maria Sherman

Last we heard from Ellie Goulding was earlier this month—the "Burn" babe shared "Love Me Like You Do," her saucy song for the steamy Fifty Shades of Grey soundtrack. (Other contributors include The Weeknd and Beyoncé...not too shabby!) And, of course, there was her track with Iggy Azalea, "Heavy Crown," for Colin Firth's latest flick. Goulding's last full-length release was in 2012, the phenomenal Halcyon. Three years later, and we're begging for more! — Maria Sherman

It’s hard to believe it’s been five years since Erykah Badu’s critically acclaimed fifth studio album, 2010’s New Amerykah Part Two (Return of the Ankh). The singer hinted at a new album as early as 2013, when she said that she was writing and that it "sometimes it takes a little while." In April 2014, she was in Africa laying down drum tracks for the new project. When she played Essence Music Festival in New Orleans in July, Motown Records had digital advertisements around NOLA's airport touting “Erykah Badu - New Album Coming Soon.” Her past couple albums have focused on political, then personal, so what can we expect from her next? Considering everything that’s been going down in America (and the world) in the five years since her last project, it’s safe to say Erykah will have a thing or two to say about it all—and we're so ready. — Mark Sundstrom

The boy band broke a record last year as the best-selling K-pop act on Billboard's year-end charts ever...and all they released was an EP! With a new full-length said to be on its way, we're excited not only to see how the guys fare on the charts, but also what amazing choreography, hairstyles and fashion they'll rock too. "Overdose" was great, but we're ready for more. — Jeff Benjamin

From saving rock and roll to embracing 100 years of pop culture, pop-punk heroes Fall Out Boy return with a fierce new full-length, American Beauty/American Psycho. The album arrives on January 20, ten years after From Under the Cork Tree, FOB's first step towards mainstream fame, and feels, well, like a decade has passed. You won't find palm-muted power chords on this bad boy, but instead you get arena-sized classic rock bangers filled with horns and choirs and all that good stuff. — Maria Sherman

Lana Del Rey's favorite rock star is set to release his sophomore effort via Sub Pop, and I Love You, Honeybear invokes the same inventive instrumentation and elaborate storytelling that Father John Misty's debut, Fear Fun, brought about in spades. That, and Josh Tillman has the voice of a super articulate angel who whips out lines that work seamlessly with whatever melody he's conjured up. "I want to take you in the kitchen/Lift up your wedding dress someone was probably murdered in" set to the romantic strains of a mariachi band? Yeah. We're sold. — Hilary Hughes

The Dutchess is back! Last year Fergie returned via her addictive, DJ Mustard-produced "L.A. Love (La La)" single, and a full-length is expected to come early this year. With another Top 40 hit under her belt, the Black Eyed Peas singer has talked about a wide-range of influences, saying she hears everyone from Amy Winehouse, Jhené Aiko and Ed Sheeran to Guns N' Roses and old-school rap acts in her songs—so expect another multi-genre approach. Ferg has revealed that Mike Will Made It, Rocc Starr and, of course, will.i.am are on board for production so far. — Jeff Benjamin

Move over, Little Mix: There's a new girl group in town! The X Factor-powered ladies of Fifth Harmony have yet to release a full-length album...but that's all about to change. Reflection, their ode to loving yourself, is scheduled to drop February 3, just in time for their spring headlining tour. Let's hope all the jams are "Sledgehammer"-level excellent. — Maria Sherman

It's been more than two years since Frank Ocean dropped his GRAMMY-winning Channel Orange, and over Thanksgiving the singer gave the first taste of new music with "Memrise." The static-y, falsetto-heavy track was a short two minutes, but seemed to indicate an atmospheric (and rather sexual) direction for Ocean's upcoming LP. Details are sparse, but we've been getting pics of the R&B star in the studio since early last year with Pharrell, Danger Mouse and Hit-Boy, who are all rumored to be on board. — Jeff Benjamin

We were preeeetty sure that a Gwen Stefani solo record would drop in 2014: She was in the studio with Pharrell, she was in the studio with Diplo, she joined the judges of The Voice and she hopped onstage with Pharrell at Coachella during his star-studded set last spring. Gwen was making a play for pop consciousness, and she followed it up with the hugely catchy "Baby Don't Lie" and "Spark The Fire" before the year came to a close. World domination is up next in 2015, and we can't wait to see Gwen's long-anticipated solo effort come to fruition. — Hilary Hughes

Imagine Dragons shared "I Bet My Life" in October of last year, previewing their soon-to-be massive full-length Smoke & Mirrors, out Feb 17. The song is a heartfelt ode to frontman Dan Reynolds' parents, almost an apology for being a jerk to them when he was young. It's something most people can relate to (those damn teen years!). The track is a slow build but has been climbing charts everywhere. If it's any indication of the rest of the record, we're in for a real treat. — Maria Sherman

After announcing "a break from music" in 2011 and taking three years off, one of the strongest voices of the last decade finally returns to us. The multiple GRAMMY nom-holding Sullivan comes with Reality Show on January 13 and brings the fighting Jazmine spirit "Bust Your Windows" fans fell in love with on lead single "Dumb." It's a strong start, but the album's centerpiece is the brilliant songwriting that sees Sullivan's signature raspy delivery pushed to new places to best tell these deeply honest stories. — Jeff Benjamin

JoJo hasn't released an album in years, due in large part to her messy label contract. It's been rumored that the "Leave (Get Out)" singer will make her triumphant return in 2015, and we hope that's the case. Last year she told MaximoTV that she started writing an album in April, hoping to put "on a new single early next year." Now is the time, ladies and gentlemen! — Maria Sherman

The good news? Kanye's new album is finished. The bad news? Nobody knows when it's going to drop…including 'Ye. The rapper talked to GQ in May 2014 about maybe releasing music in the fall, but nothing's surfaced yet, and Yeezus admits he "goes back and forth" about release dates. Alt-rap star Theophilus London tweeted in September that he's on the first single, and after Kanye hosted listening sessions at 2014's Paris Fashion Week, the album can't be too far off. The New Year's surprise of "Only One" featuring a very quick cameo from Paul friggen McCartney (!!!) seems to indicate an 808s & Heartbreaks-esque return to AutoTuned 'Ye. — Jeff Benjamin

After giving birth to her first child, the original American Idol appears full of light and ready to bring her feel-good, pop-rock sound back to radio. After an adorable teaser featuring her newborn daughter River, Kelly kicked off her new album promo with "Heartbeat Song," a racing, shout-along rock-pop track with an addictive chorus. Clarkson has since teased other details about the LP, describing it as pop, but adding there's elements of rock, country, R&B and dance on it. She also teased a duet with a male singer she's collaborated with in the past (Blake Shelton? Jason Aldean? Justin Guarini?) and a possible song penned by Sia. — Jeff Benjamin

About time! Kendrick Lamar was a major player on the festival circuit the past two years following the 2012 release of good kid, m.A.A.d city, but he never really released any new material. Last year he shared the Isley Brother-sampling "i," but other than that, all was silent. The rapper told Fuse new music might arrive alongside the launch of his new Reebok sneaker...and has since confirmed a new album is on the way. — Maria Sherman

The last time we heard new music from singer/songwriter Keri Hilson was with No Boys Allowed in December 2010. We have proof Keri’s been hard at work on her follow-up album for a few years now, and rumors are Miss Keri Baby is dropping it this year! Just a few weeks ago in a red carpet interview with VegasNET Media before a show at Chateau Nightclub in Las Vegas, Keri said, “I haven’t seen my fans in awhile, but I’m on my way back, officially now! It’s 2015 – I’m very excited.” If this new project is on the same level as the first two albums, we’re pretty damn excited, too, Keri. — Mark Sundstrom

Something tells us Kid Rock's First Kiss isn't going to be about those first innocent forays into romance, but hey: It's not a Kid Rock production without a little raunch, right? His first album since 2012's Rebel Soul is sure to bring about more of the Kid's redneck pride and sensibilities, given that the track list so far includes tunes called "Johnny Cash" and "Ain't Enough Whiskey." — Hilary Hughes

Madonna has done a good job of keeping Rebel Heart (out March 10) under wraps (despite the fact that somebody leaked it in full last month) sharing few details of the album save for a few Instagram posts and, of course, the very public announcement that she was heading into the studio with EDM guru Avicii. Last May she revealed she was working with Diplo, and in July, teased a track titled "Messiah." The song is very current yet very Madonna, electropop by the pop mastermind herself. — Maria Sherman

It's been a minute since a few shocking screams/distorted riffs/all around dark and dangerous debauchery through an amplifier have made their way out of Marilyn Manson's camp and into the ears of his fans. But that's all about to change. The Pale Emperor is set to drop January 20, satiating Manson fans for the first time since 2012, when he released Born Villain and spent the majority of his time on the road touring behind it with Rob Zombie and Alice Cooper. Manson worked on Pale Emperor with one of 2014's unlikely major music mover and shakers, Tyler Bates, who's responsible for the amazing curation of the Guardians of the Galaxy soundtrack. Basically, Manson's not messing around, and we can't wait to hear the high-drama results of The Pale Emperor. — Hilary Hughes

While Jessie J and Rita Ora are on the cusp of breaking into super stardom stateside thanks to major collaborations, there's one singer from across the pond we really want to see explode in 2015: Marina Diamandis of Marina and the Diamonds. Electra Heart and The Family Jewels were perfect explorations in feel-good pop, and Froot is sure to be much of the same. — Hilary Hughes

Everyone got vintage R&B fever when Bruno Mars lent his voice to Mark Ronson's latest insta-hit, "Uptown Funk." The tune comes from Uptown Special, Ronson's first record since 2010's Record Collection. Every live performance of "Uptown Funk" has kept audiences dancing and belting along with Bruno on the chorus, so if that's any indication as to what's in store for the rest of the record, we'll be dancing long into 2016 thanks to Ronson's throwback stylings. — Hilary Hughes

With "All About That Bass," Meghan Trainor skyrocketed to the top of 2014's charts—and she did so on the strength of that one single that didn't even have an album behind it. That record is coming, and Title, Trainor's first full-length, is set to capitalize on the boisterous and blazingly addictive beats that started with "Bass" and carried on through "Lips Are Movin." Rest assured, Trainor's success isn't something that got left behind in the the last calendar year, and Title is set to prove it. — Hilary Hughes

Even if "Float On" is the only Modest Mouse track you're familiar with, you're bound to be stoked on the fact that the Washingtonian indie rockers are back at it for the first time since 2007's We Were Dead Before The Ship Even Sank. Modest Mouse made a few select festival appearances in 2014, and it was all a precursor for Strangers to Ourselves, which is set to drop March 3. So far, "Lampshades on Fire," Strangers' first single, is just as buoyant as some of the most beloved selections from their catalog, so here's hoping the days on the calendar start flyin'. — Hilary Hughes

The British singer-songwriter is no stranger to switching things up, and her ninth studio album has an experimental twist: Harvey will record her album publicly behind one-way glass as part of an art installation at London’s Somerset House. Working with longtime collaborators John Parish and producer Flood, Harvey has said she hopes “visitors will be able to experience the flow and energy of the recording process.” Viewers will witness a random part of that process in their 45-minute viewing slot, anything from monotonous orchestral tuning to entire songs performed from start to finish. — Samantha Vincenty

2014 was the year without Rihanna. With the exception of the undeniably sexy "Can't Remember To Forget You" with Shakira, Queen RiRi gave us nothing...making the world hungrier for her songs than ever before. Rihanna's next album is believed to be titled R8, and while we don't know much about the release, we can expect tons of collaborations and new, edgy pop sounds. Check out our complete guide to the record here. — Maria Sherman
