Can I change around the songs on the FoF CD itself so I don have to keep swapping out?
Nope. This wouldn’t normally bother us so much, but there is a distinct possibility for someone to build a clandestine copy of FoF which has a hundred DDR songs on it and release it that way. The game was really built in “no user servicable parts inside” mode. If you extract songs from the release version of the game (we’re not silly, we know you can do it :), we’d like for you to refrain from distributing them. Many of them are created by third-parties and they requested that the songs only be distributed with FoF.
