What a bizarre little title!
Take REZ and Guitar Hero, add the option people have been NAGGING for (own music) and what do you have?
One BIZARRE on-rails game!
(Closest thing I can place it as? Breakout on L.S.D!)
The tracks literally CHANGE *depending* on the music you use!

try the Beta, it works fine, just be warned that 1) It lets you try YOUR media ONCE and 2) It'll need to update before you play the first time.
Aside from that, it's awesome!
(I'm just kicking myself for accidentally clicking "I'm not driving anymore" by Rob D. for my one and only Beta version song!)
