Just a thought....
Apologies if this has already been said, no real interest in trawling through all of the comments so far, but:
I use iTunes due to having an old iPod and being too lazy to investigate alternatives, I have in the past (don't shoot me) enjoyed the occasional track from them so opened it up to give it a listen and see if there was anything worth keeping. With my setup it hadn't downloaded at all, I had to go into the list of purchased items and select to download it before it synced, without investigating at all I'm wondering if most iTunes users have their account set to sync everything without confirmation?
Still haven't bothered to listen to it though, but was it really worth all this fuss? They gave something away for free, if you don't want it just delete it. I can't help but wonder if the same level of fuss would have been made if the artist in question was a bit more popular.
