I haven't bought many since the price has gone over $10/ea in general. Really none... unless you count a few childrens CD's for our daughter.
If the price had dropped to $5-7 each I'd occasionally buy some, but, not as much as I did in my disposable-income-20something days. But at least I would consider it. At the prices I've seen lately $15+ they can suck it.
I don't care about the file trading issue, I'm not saying the price justifies stealing it. I won't buy CD's at the prices today even if all file sharing was stopped. To emphasize the price point issue further... I buy DVD's for $10ea all the time, I'm starting to build quite a collection. Sometimes I'll spend a bit more. Usually I buy them previewed for an avg price of $7ea at blockbuster. But even new at $20 I don't feel raped buying them.
There's no way I believe that the cd needs to cost $15... and I refuse to spend that much on one. $10 is still too high. I can get a LOT of good movies for that price, much more enjoyment than a $10 CD. $7 TOPS for a NEW artist or a Greatest Hits CD, and $5 avg for other slightly older discs would work for me.
RIAA is suck.
