oh, actually, it'd be nice to have a workaround in the game so that it can run on the press units currently out there without them having to update. I've found that having one frame, or 2176 samples, of silence at the beginning of the file gets it past that decode error in the first frame. I think just other_middle.mp3 and outro.mp3 need this. The worldX.mp3 files seemed to play okay. I'm happy to fix those up and push them to the git repo if you'd like.
