I just never understood its success... the convenience seems to come at a tremendous price. Why would you pay $10 for an album's worth of ephemeral, DRM-encrypted, 128k AAC audio files when you can go to half.com, buy the used album on CD for $5 or less including shipping, and always have a pristine uncompressed digital copy, plus authentic printed liner notes, that will still be there when your harddrive crashes, that you can always rip into any format you choose, even 10 years down the line when better-sounding lossless compression formats are in vogue and DRM'ed AAC is a format of the distant past that no modern electronic device can decode? It always seemed to me that buying iTMS music was a great way to give yourself the shaft. What's the scoop on this poop?
