Miley Cyrus and Justin Bieber collaborated on a track called 'Twerk' with Bieber's bad influence buddy, Lil Twist -- and the song has leaked to the web.

What does it sound like? A relatively catchy death knell for civilization.

Bieber croons, "I valeted a car / Throw me the keys / It's time to go / You're coming with me / I've been looking for you for a while."

Meanwhile, Cyrus takes over for the hook, which echoes her entire being for the last few months: "I'm up in this party / Time to twerk / I came up in this party and I'm turnt." The chorus then falls into a rapid repetition of the word "twerk" that may or may not be a deliberate self-parody.

As for Lil Twist? He acts as a hypeman on his own track, just introducing his featured superstars and occasionally mumbling softly in the background, which doesn't do him any favors in being known for anything other than a Biebs-hanger on as of late.
