I think it’s really cool that a self-releasing artist can now easily click through to an album release among most of the “usual suspects”. I think this is a creative approach, and I hope it succeeds.
I think that what we have in CD Baby and Tunecore is a template for future record labels. These are more or less self-service agencies for musicians. The model is that musicians direct their own roadmap and pull services from agencies like CD Baby and Tunecore as needed.
The other path for record labels to take is to be something like the game industry, where small shops do the creative work under their own power and then cut deals with the behemoths to get their work distributed.
