Best for MP3 Downloads

Amazon.com boasts a large library of more than 13 million songs, comparable to that of iTunes and topping Napster. Its DRM-free MP3 tracks are playable on virtually every music player, including iPods, so this is a good… site if you don't want to be forever tied to iTunes or another proprietary format. The site's AmazonMP3 Downloader will automatically transfer your purchases to iTunes or Windows Media Player if you choose. Like iTunes, AmazonMP3 doesn't have a subscription service, but Amazon's prices for tracks and albums are often lower than Apple's.
