The game advertises the ability to use your own music, but it doesn't seem to work proparly. I tried about a dozen tracks from Noiz+Zilenth, Terrorfakt, Xotox and other rhythmic noise artists, and the game doesn't seem to catch the beats properly. This could be because the heavy distortion in this kind of music screws up the software they use with the game, however. The game is a cool concept, but the inability to use the kind of music I enjoy really kills it for me. I don't like the music the game has by default, but a lot of people seem to - if your like the music in the trailer, I actually suggest buying it. If you don't, proceed with extreme caution.
