Between Vampire Weekend enlisting Jonas Brother Joe Jonas to star in their "Giving Up the Gun" video and a burgeoning war between Justin Bieber and Raaaaaaaandy (aka comedian Aziz Ansari), it looks like the indie world has finally figured out how to capitalize on the current teen-pop boom.

As we wait on the official release of Raaaaaaaandy and TV on the Radio producer-guitarist Dave Sitek's hip-hop mixtape, the duo have a new video on Funny or Die that claims Canadian moppet Bieber shot Raaaaaaaandy in the knee and stole a Raaaaaaaandy track called "Baby Baby" and turned it into his smash hit "Baby". Yeah Yeah Yeahs' Nick Zinner makes a guitar-swaying cameo in the skit.

Check out the first track from the mixtape, "AAAAAAAANGRY", here. Download Raaaaaaaandy's "Baby Baby" and watch the Bieber vs. Raaaaaaaandy saga below.

And-- because this is the only chance I'll ever get to embed a Justin Bieber video on Pitchfork-- the original "Baby" video is after the jump, too. The kid really let himself go:
