I've been listening to last.fm a lot lately and I notice that songs it suggests to me, that I like a lot, happen to be available for free at http://www.ektoplazm.com/ http://www.ektoplazm.com/. There's no obvious way to even buy them. I like 90s Israeli Goa trance and it seems that a lot of people are making it and releasing it for free just because they love the music. Besides, the equipment and recording costs are negligible. Since this is the case in the free software world, why shouldn't it take hold in the music world too?
