You can listen to the NPR story "The Music Industry: Adapting to a Digital Future" here:
One thing they talked about was a website I've found called "TuneCore". Unlike CD Baby, after you pay a very nominal amount to get your music uploaded and distributed for possible inclusion by such distribution entities as Amazon.com mp3 music downloads, iTunes, etc, you get 100% of the money that comes in for your songs.
There is still a place for the major labels marketing in some scenarios. On the NPR program they discussed the fact that yes, getting "findable" on myspace.com and the other Internet music sites is the hardest part. But people are doing it every day. And the labels kick in best when the artist has already garnered a following. (The contract is also much more artist friendly!)
It is so incredibly economical these days to create, market and distribute music, if you really want to learn the ropes for the Digital Age. Research the web by setting up "Google Alerts" for music business, music industry, digital technology for selling music, etc. Read blogs like the Listening Post. Buy a round of training with Internet music sales gurus like Bob Baker . And comment on this blog when you find something interesting!
