the only way that ive found to play this game offline is with created beats, and you have to put a copy of the mp3 file in the var/root/media/ttr/music folder. its kind of a pain in the ass, but its offline. so if your interested,

first create your beat (it will save to the ttr/taps folder as something like phonename.a bunch of numbers.tap)

using ibrickr, download the .tap file and change the name to the same as the mp3 which you put in the music folder.

upload the renamed file into the taps folder and get down on some offline action.

hope this helps someone...
