my problem is price. a dollar a song is too much. and no matter what format you buhy, that's the going rate.
I buy my CD's on half.com
allofmp3.com is something like $2 per album or much less for a song. However, it's a Russian site, and I'm not willing to give them my credit card.
You can make the case that a dollar is a fair price, since it lets you play the music on an iPod, computer, home audio system, etc.
On the other hand, I see the price coming down as distribution channels increase, i.e. downloading songs from the digital jukebox at the local bar or a kiosk in the mall or giveaways with retail chains -- buy a pair of jeans from Old Navy and get two free songs -- that kind of thing.
