Lil B: God's Father
He’s a great rapper, yes, but he’s a true master of YouTube self-promotion. Lil B’s mixtape might be a tad too much at 34 tracks, but when he’s good, he’s very promising. [DatPiff]

Madonna: “Love Spent”
I was really excited when I saw another new Madonna song was previewed online. After listening to this one-minute tease, I’m decidedly less ecstatic.

Sleigh Bells: "Irreplaceable" 
Hardly as good as Chairlift's Beyoncé cover. In fact, it's kinda blahhh. But listen to this acoustic cover from the usually noisy duo and decide for yourself!

Sufjan Stevens & Rosie Thomas: "Where Were You?"
The prolific indie oddball is developing a troubling Auto-Tune fetish, first seen on his three-way collaboration earlier this week and now on this duet with the Michigan singer/songwriter. The music sounds like early, gentler Kraftwerk though, which is cool. 

Trouble: "Let Them Tell It" 
The talented up and coming Atlanta rhymer calls out, well, most other MCs for pretending to have more street cred and more money than they actually do. [TheFader]

Suckers: "Turn on the Sunshine" 
The first track from the upcoming Candy Salad is a sunny delight, but without the weird aftertaste of actual Sunny D. [Pitchfork]

Obie Trice: "Love Me"
He never truly broke through despite Eminem's backing, but the Detroit rapper hardly ever disappoints when he steps up to the mic. [XXL]
