Of note: some labels have started charging more for both singles and albums, although to date services have only passed on the higher charges to consumers who purchase albums; Walmart.com's 88-cent music store has come the closet to duplicating Apple's success, with the store garnering about half as many customers as iTunes had in March; and Apple's competitors continue to believe that Apple's closed approach to the iPod/iTunes will be what unseats both from their dominant positions, while the music industry itself would like to see more interoperability between all services and devices.
