Beck Ready to Confuse in a Whole New Medium

Ah, Beck. A fantastic manga and anime, whose title inevitably confuses people because of Beck the musician and Jeff Beck the other musician. Now Beck is on its way to becoming a live-action movie, and should baffle a whole new audience trying to understand if either Beck is actually involved. I’ve enjoyed Beck, and there’s nothing about the trailer that makes me not want to give the movie a shot. My question is who’s actually doing the music? Are they using the same songs from the anime? Is someone composing all new music? Who’s playing it? Will they still be using Beat Crusaders’ “Hit in the U.S.A.”? Because that song is awesome.
