I think you might want to join Hollywood's netlabel. It's got a lot of chiptune artists!
.about monotonik + friends.
Monotonik is a net.music.label that _exclusively_ releases music online in the mp3 format. All of our releases are freely downloadable and distributable, and we've been releasing .mp3 and .mod files online since May 1996. The label was founded by h0l as an outlet for talented electronic musicians who weren't getting the attention they deserved.
