Yeah celebrian, but for the single track, I'd go with iTunes. Totally see your point though.
I have been reluctant to buy from the iTMS because whether or not I can tell the difference, I know it's there. I don't have a hi-fi system or wonderful headphones, so I know I wouldn't be able to tell a 192k from a disc, but I would know it's different, and if I ever do get a hi-fi system, I'm screwed, because I am almost positive that I'd be able to tell the lossy compression up to 192 or so.
I haven't heard it mentioned either, but I collect live music, all of which is only traded in flac/shn... ONLY. Simply because you don't know what someone has done to mp3s and it's quite possible that they have been re-encoded and the quality compromised. This is great news for me since I have over 2000 hours of music archived in Apple Lossless. If the industry swings this way, this would justify all my re-encoding to this format.
One final thing... Apple Lossless will be about 3-4 times the size of an AAC file. How long until bandwidth and HD space increases by that much? A few years. Plus blu-ray and HD DVD are coming to give you more archival storage. The size is worth it! Forget 192k etc. Go with 128k lossy, or lossless. Keep it simple. I like how it's done at livephish.com, you can buy flac or mp3, slight price difference.
