Wired has a good article up about the various digital music vendors: Urge, Napster, Rhapsody, eMusic and iTunes. They compare and rate the services. In the end, they chose iTunes as their editor's pick, pointing out that although iTunes has no subscription plan at this time, its combination of easy-to-use shopping plus the huge catalog of music, TV and video makes iTunes the most compelling digital vendor. At the bottom of the pack was Napster with its three-device playback restrictions and limited device compatibility. eMusic won on pricing (about $0.25 apiece, if you buy all the tracks you're allowed) and their DRM-free tunes.
