Reviewing digital music stores is like reviewing a movie in production. During the few weeks I have worked on this review Musicmatch overhauled their music store pages and corrected a bug, Apple corrected an annoying "feature" of their jukebox, and Wal Mart opened their own music store. As companies compete for market share you can expect rapid changes from each of these services to stay competitive. New competitors such as Amazon and Microsoft would change the landscape even more. It should only be good news for music buyers.
