Remixin
In this article Ernest Miller suggests that remix construction sets (such as the Jay-Z Construction Set) are the future of music. He compares it to gaming mods, which is an interesting comparison. This sort of thing has actually been going on for a while now, specifically in the Acid community where artists like Madonna and Beck have been offering up the source files for some of their songs in remix competitions for years now (there are even prizes).
When I originally started doing this net music thing I started offering my own full bloated source tracks on CD for $5. I thought it'd be a neat way to get people involved and engage listeners and also get across that I don't care too much about copyright (for the nerd cred). But hardly anybody ever bothers with those things and when I eventually revise my FAQ I'll probably take the offer out because it doesn't seem to accomplish anything.
I've been giving some thought to chopping up my album into loops so that it's smaller and easier to distribute without having to mail actual CDs around but I'm not sure if it's really worth the hassle. Are there really a ton of would-be remixers out there?
