Well let's put it this way : having to install iTunes to buy one track is a fucking drag and stupid in its own way.
If you're not using the whole Apple line and environment, iTunes is a useless POS, and not being able to - at least- just buy the thing from the artist himself instead is dumb.
I'd love to get to hear the track, I'd love to buy it, but that's just way too many hoops for 8 minutes of contextual droning.
