We didn't say this was going to be easy. This is from the album cut "Stole My Heart," from One Direction's debut album 'Up All Night.'
Another 'Up All Night' favorite, this one is "Tell Me a Lie." Fun fact: Kelly Clarkson originally wrote and recorded this song before passing it on to 1D.
That swoon-worthy lyric is found on "One Love," off of Justin's 2012 album 'Believe.'
Even though that might be a mindset Bieber embodied these last years, One Direction sang them on their "Act My Age" song off 2014's 'Four.'
Bieber may own the Beliebers and have an album named 'Believe,' but 1D sang this lyric about becoming a believer. It's from their 2012 album 'Take Me Home.'
Of course Beliebers would know this is Justin Bieber on "All That Matters," a track off his underrated 'Journals' collection.
Bieber again! This is from fan favorite "Up," off his first full-length, 'My World 2.0.'
That's Justin with "Thought of You," off his 'Believe' album.
This one might also have a Bieber theme, but it's 1D! This is also off their debut album, 'Up All Night.'
Did we trick ya? While the lyrics are similar to One Direction's hit "Steal My Girl," this is "Runaway Love" by Bieber off his 'My World 2.0' LP.
Did we trick you again? This IS "Steal My Girl," which you remember becoming a Top 20 hit back in 2014.
That's JB on "Catching Feelings," another fan favorite on 'Believe.'
This is lifted from Justin's Lil Wayne collaboration, "Backpack," off his 'Journals' release.
That's of course One Direction on 'Four' standout "No Control," a song fans begged to be released as a single.
That's from One Direction's "Half a Heart," taken from the 2013 album 'Midnight Memories.'
The Biebs serenaded us with promises of hugs and kisses on "Right Here," his 'Believe' single featuring Drake.
1D did! They sang these lines on "Don't Forget Where You Belong," another great 'Midnight Memories' cut.
For the super Directioners! This line came from "Loved You First," a bonus track off 'Take Me Home.'
