We can't stress it enough: BBC Radio 1's Live Lounge is the gift that keeps on giving. The series introduced us to the wonder that is Ed Sheeran covering 5 Seconds of Summer, Demi Lovato rocking Hozier and Taylor Swift tackling Vance Joy...truly, the list goes on and on.
They make the tune their own, adding real-time sax. It makes the song a little bit jazzier, a little bit more rock 'n' roll. It's not like we haven't seen this before, in the Live Lounge, when frontman Matty Healy and crew tackled One Direction's "What Makes You Beautiful."
While we've got you, make sure to check out our list of the 16 pop albums we just can't wait to hear this year.
