This is an interesting article in which 8 UK artists swapped iPods, and then were asked to comment on the music and guess whose player they had.
Guardian Unlimited | Film & Music | ‘What? You call this music?’
The interesting tell in it for me was that the three that made references to whether or not they would acquire the type of music on the iPod they got, all used the word “download” instead of “buy”. “That’s not the sort of thing I would download” or “I would download that.”
