I can see this catching on at my school, everyone just screws around in the other games but maybe they'll start taking it seriously when there's killing involved.
wait, if badges are released, does that mean theyll be stuff like (e.g.)
easy: have a song with +10
medium: have a song with + 25
hard: have a song with +50
impossible: have a song with +100/+200/+250(i dunno)
