I buy nothing.
However, the reason is not p2p. It is quality (or the lack of).
For instance, since this is the 21st century, certain music I would pay for. As an example...
'Elvis Aloha from Hawaii via Satellite' (don't make fun please, I happen to think that was the peak of Elvis's talent and career, and so what? I like Elvis. lol) I would pop a woody IF I could purchase a cd of that redone from the original 29 track master into lets say dolby surround 5.1 . Can I buy that? Hell no. Not even for one million dollars. I would happily pay $20, but guess what, the record companies aka RIAA are entirely too cheap to produce anything involving Quality. WTF is their problem?
Do they think it's more profitable to simply whine and bitch how they aren't making money the way they used to back in 1973?
Offer something worth buying, then maybe people will buy.
Ordinary cd type music, and mp3s as well, are far below what Could be done with todays technology for even the oldest music.
Even the ancient original album pressed from vinyl of the above mentioned concert is more advanced than what there is available today. It at least was made in 4 channel quadraphonic stereo and without sillyness like mega compression of dynamic range to make it 'sound louder' like is so popular now.
Maybe some buy more music after a download, but not me. The slight increase of quality offered by a cd Vs. an mp3 of the same 2 channel, purposely compressed music isn't something I think I want to waste money on.
