IODA

To quote the site:
"IODA (Independent Online Distribution Alliance) is the industry-leading digital distribution company for the global independent music community.
Run by an experienced team of digital music and technology experts with a passion for independent music, IODA is the premier digital distribution and marketing company for independent labels who want to build and grow their business."

I cannot vouch for their success at marketing...because I've never used their service. The business model inhabits the world where music is a product -- but they seem to be positioned to exploit (in the best sense) the opportunities of "music like water."

There are many things that can be learned from these guys' website if you were a student of music business!
