Justin Bieber and Selena Gomez, "Strong"
As exes, Justin Bieber and Selena Gomez are two of the last people you'd expect to hop on a track together. And yet Drake's OVO Sound radio show got hold of a mysterious duet from the two former flames and premiered it over the weekend. Like Britney and Justin before them (#neverforget "What It's Like to Be Me"), together the two are a force.
Chairlift, "Ch-Ching"
Charli XCX, "Vroom Vroom"
Demi Lovato, "Yes"
There's a lot of talk about "Stone Cold," a ballad from Demi's latest album, which she also performed on Saturday Night Live this past weekend. But the real winner of her album is "Yes."
