The fine fellas at Songfight pointed this article out to me, which talks about a lot of the lack of music filters on the net that I was complaining about the other day. But unlike me who just whined, this article actually pointed out a few neat things, like this iRATE software:

One promising though unpolished piece of software for finding new music is called iRATE Radio, created by a New Zealand computer programmer named Anthony Jones. It serves up a steady flow of legal MP3s from sites like IUMA, which are then rated by the user.

I haven't had a chance to try it yet, but I think it's great that people are working on this sort of stuff, seeing the potential in the net indie scene, etc, etc, blah blah.
