Yeah, I agree with Legion, a lot more thought could be put into this. Nice concept. Needs more questions, and instead of just logos and clues towards the band name, maybe put song titles, album names etc. It wouldn't hurt to add music either, or a "back to main menu" button at the end. 2/5 for same reasons as Legion.
This game is good, but not good enough for badges. Plus, it probably doesn't have Kongregate API, so there is no point begging when FOG isn't going to change it.
