i'm always amused by the people who said that eMusic abandoned the indie music fan when they added major labels... it certainly didn't stop people from downloading all the major label stuff and all the exalted indie labels/bands everyone carries on about are all pitchfork approved "indie"... you rarely ever saw CDBaby indie releases topping any off their charts.
i know emusic has lots of detractors but it absolutely worked for me. i easily follow 50+ labels via the site and never have a problem get my months credits worth. many of those labels who do not have domestic physical distribution, so eMusic was a way to get at a reasonable price lots of my favorite recent releases. i have bought a total of five tracks via iTunes, a handful via Amazon and Bandcamp.
