I use different Creative Commons licenses to release my work. Some folks only use attribution non-commercial licenses that bar commercial uses without a license. I do that sometimes, but I prefer to release my work Attribution only, to permit commercial uses. Sometimes, I require share-alike, which tends to make things a bit less commercial.

I share electronica music using Creative Commons licenses. My work gets used as background sound and fury in pieces ranging from home-made youtube posts to commercial films and public radio podcasts.

I use freeware, shareware, simple commercial-ware and imagination to create songs and ambient pieces which serve as the background for daydreams around the world.
