Feel free to add your thoughts and comments on the song choices. The first three are songs I would most like to see in game at some point, and the first two seem like they'd be good for all instruments including keys.
99 Luftballoons- Nena
Love Missile F1-11- Sigue Sigue Sputnik (Can't find a good version of the original mix without the music video effects mixed in ruining it.)
Kids In America- Kim Wilde version (I hate the version by The Muffs, personally.)
Shout- Tear For Fears
Wake Me Up Before You Go-Go - Wham!
Sunglasses At Night - Corey Hart
Another Brick In The Wall - Pink Floyd
Party All the Time- Eddie Murphy
The Reflex- Duran Duran
Hip To Be Square - Huey Lewis & The News
