I would pay 10 cents per track, but I'm used to paying a lot more. Now days that's probably high.
I think people are going to stop using i-Tunes. To me, the DRM is more annoying than the cost. Amazon has a very big selection that's DRM-free and at a higher bit rate.
Plus, people are investing a lot in the future of Apple and Ipods. Just think where we'd be today if Sony sold cassettes and CD's that only played in Walkmans and Discmans. I can't believe people pay full price for AAC songs that you have to convert (losing quality from average quality AAC files) to play anywhere other than their computer or Ipod.
DRM'ed files don't bother me if I'm not paying for them or buying a subscription. They should never be on a song you payed full price for. DRM'ed files also bother me when they aren't able to be played on any player. There's Apple rearing it's ugly head again.
