You know, I've been wondering, since the AAC codec supports 5.1 surround sound, do you think Apple will eventually utilize it for music? I noticed that many trailers on the Apple QuickTime site have 5.1 audio. It would be just be freakin' awesome, and for each song, they should charge basically maybe 50 cents to 1 buck more than usual. Or for an album, maybe 15 to 20 percent more. A small premium to pay, but if we could get surround sound, the iTunes Store could really push it, compared to ill-fated formats like SACD and DVD Audio. What do you guys think?
