I just spent about 12 hours scouring nearly every royalty-free music site on the net for music I can use with Joystick Johnny. Specifically, early 80's-style electronic music. It's been... um, an experience.
Out of the 20 or so songs that I managed to excavate from 50 websites and 1000's of modern techno songs, nearly all suffered from at least one of the following:
1) Too slow
2) Too short
3) Too Musak-ish
4) Not electronic enough
5) Good 80's feel, but the composition was bland

"Take Me Down" is particularly good.)

So, I'm back to my original plan of writing the music myself, which means it'll be almost entirely devoid of melody and have a lot of drums. Also, it will sound very electronic, to match the electronicity of the game itself.
Here's the tentative track list:
In-Game Music
"Yeah Yeah"The end song from Ferris Bueller ("Oh Yeah") meets breakdancing music
"Miami Heat"Hello, Jan Hammer
"Blip Monday" (12" Mix)Very chippy, with some New Order and Soft Cell mixed in
Boss Battle
"Please Don't Retreat or Surrender"A lot of Hex Drums and low blatty synths
Victory Tune
"Top Dog"In the style of the Top Gun theme song
