When I was in Seattle the big buzzword everyone was throwing at me as a little net musician was Podcasting. I don't own an iPod so I automatically disqualified myself from being interested in it. I've had a chance to read up on it now though and it's really just aggregated audio content, which I am a fan of. You jam audio (generally audio you make, radio shows, etc.) into your RSS feeds, and then there are tools such as iPodder to automatically download this content. As a next step it'll cram it into your iPod so you can listen on the go.
As a net musician, priority number one is getting my dumb songs out there to as many people as possible. Without a giant budget I have no sure-fire way to get onto the radio, so obviously the idea of a free opt-in broadcast service is nice and exciting.
Thanks to Pieter Overbeeke and Bernard Flach's enclosure modification for Wordpress (which Pieter verified to me works fine with Wordpress 1.2.1), I've added enclosure support to my latest song entries. This feed here should get you the latest Brad junk into your aggregator. The main feed will now have enclosure support for my songs as well alongside my regular postings.
I'm also trying to figure out a way to move all the remixes people have done with my source files over into a feed of their own as well, but that's being a bit trickier.
