OK well maybe not. But based on the way Apple’s email to me crowing about iTunes Plus options on the iTunes store makes it sound you’d think they’d gone to mp3 format for those selections. I quote:
With high-quality 256-Kbps AAC encoding and no DRM (digital rights management), the iTunes Plus catalog is the largest DRM-free catalog in the world. And that means you can play iTunes Plus music on any iPod or other digital music player and an unlimited number of computers.
“Play music on any iPod or other digital music player” (emphasis mine). Surely they jest. The only other player I know of that currently plays AAC is the Zune. Apple certainly chose interesting phrasing. It sounds on first reading that these files will work with any player, iPod or otherwise. On second reading I’m not sure what they’re saying.
Whatever the case woe to the person who buys tracks off the music store only to find out that they don’t actually play on most other players save for the iPod lineup.
