Do you like any songs that you play when you play canabalt, or songs that match the theme? So far I can think of the song "too fast for love" by Motley Crue. Any others you can post below....
Caustic Window (Aphex Twin) - On the Romance Tip Trust me on this one. Finally a thread I really like.
Bit of a stupid question, but how do you even play your own music in canabalt? I can't find the option anywhere.
8-bit music/Chiptunes are really good! Try browsing http://8bitcollective.com/ and http://chipmusic.org/
