We all know that iTunes is the undisputed king of the online music store castle, but there are a bunch of little guys fighting over the scraps thrown away by the behemoth from Cupertino. While services like Napster and Rhapsody sell music with all sorts of fun DRM (digital rights management) copyright protection that makes it impossible to listen to the songs on an iPod, upstart eMusic sells unprotected MP3 files. These files are the exact same types that are illegally swapped online willy-nilly, but because of that lack of security they can be copied to virtually any device. This gamble appears to be paying off. eMusic, despite the fact that they offer very few "big name" acts, is second behind iTunes in the online music marketplace. By focusing on more independent artists and giving their customers complete control over the files they sell, eMusic has becoming an underdog success story. Well, sort of… they have 11% of the market to iTunes' 67%, but hey, that's more than both Napster and Rhapsody combined, so give them some credit. We'd love to see more companies moving in the DRM-free direction, as customers clearly like to have the freedom to listen to their legally purchased music however they'd like.
