BBC tease

BEEB'S YOUR UNCLE: Lady Gaga, Drake, Thirty Seconds to Mars, CHVRCHES, Jason Derulo and Jessie J jump to the A List at BBC Radio 1 this week. Meanwhile, Avicii's "You Make Me," Coldplay's "Atlas," and Daft Punk's "Lose Yourself to Dance" are among the playlisted (that's Beeb-speak for "added") tracks. Oh, and keep your eye on another playlisted act, pop-rockers You Me at Six, who are tearing it up on the U.K. iTunes charts (we'll have more about that later).
