If you haven't tried out Tap Tap Revenge yet — the fun iPhone app that uses your iTunes library to challenge you — then now might be the time! One of my all-time favorite bands, Weezer, has released a version of TTR — Christmas-song themed.

The Christmas with Weezer iPhone app is $5 (regular TTR is normally free), but it includes six holiday songs by the band, plus a couple from the most recent Red Album.

It's one way to start rockin' around the Christmas tree.
