iTunes still has about 4 million more songs then Amazon currently, and also will have song potentially cheeper, at the 69¢ mark. 99¢ and $1.29 seem to be the other tiers that iTunes music will be priced at, with the note from the keynote being that most songs will shift down towards 69, rather then up to 1.29. In any case, it's good to see the iTunes store still evolving, even though it has the #1 market share for music sales both digitally, and retail overall. Always worried about the Microsoft syndrome catching on at other places, where good changes cease once a product climbs to the top.

AAC vs MP3 doesn't really bother me either. MPEG 4 vs MPEG 1 format, and these days pretty much anything plays both.

This is all assuming I buy into the digital downloads anyhow. I think I might have 30 tracks now from Amazon and iTunes combined, excluding any random free tracks I've grabbed over the ages. I still pretty much stick to CD.
