Florence + The Machine covers Justin Bieber's "Where Are Ü Now"

Justin Bieber isn't exactly my "go to" in any type of musical scenario. But, I loved his link up with Skrillex and Diplo.

FKA Twigs Covers Sia's Elastic Heart @ Live Lounge

FKA Twigs' catalouge has been on heavy rotation again since her latest EP M3LL155X dropped last month.

With such a sonically cohesive sound, I was intrigued to hear how she'd handle the distinctly pop sounding Elastic Heart, which she chose to cover for Radio 1's Live Lounge. No surprise, she ably pulled the song into her world with spacious, brooding production, delicate vocals and a little bit of performance art. Basically, she FKA Twigs-ed it.

Anyone expecting a karaoke rendition, look elsewhere. This one ain't for you. Maybe try Ella Eyre's take.

Demi Lovato Tackle's Hozier's "Take Me To Church" 4 Live Lounge

Demi Lovato's sezy new image is paying dividends, with her latest single Cool For The Summer currently wrecking charts errwhere.

[Watch] Pink Covers Alicia Keys' "Girl On Fire"

Ever wondered how Pink's edgy pipes would handle Alicia Keys' bombastic "Girl On Fire"? Well stop it before you hurt yourself, because, through the magic of BBC's Live Lounge, it is now a reality that can be heard via Youtube!

Taking the empowering, feminist mid-tempo track, Pink gives it the "Just Like A Pill" treatment: smooshing the two songs together to form one gorgeous mixed-genre baby! I just wish her vocals had been a little bit more peppy because though good, they were just missing that fire- which Pink usually has in spades- needed to sell the lyrics fully.
