Want some random goodness?
Go to this brilliant site, http://chiptune.com, and open Tools -> Random Chip... It will download to your hard drive a ZIP containing randomly selected tunes in many formats
thank a lot for the link \o/
If you don't like the interface (I know it's a pain to use), you can still access the database by using my old Chiple, or simply use the ftp
I carefully selected one by one all the tunes you can find on chiptune.com, so I can recommend every tunes
I think my two personnal favourite chiptunes are:
Monday by Random Voice (Amiga mod, 4 channel)
Hybrid Song 2:20 by Quazar (PC xm, multi channel)
