I tend to agree but look at the overwhelming number of re-packages and re-issues, 'greatest hits' etc. along with mix compilations that ensure one-hit wonders stay that way.
It's a chew-em-up-and-spit-em-out game and I'm in the same boat as you as it's nearly impossible to find a lot of late 70s/early 80s power pop - it's all out of print. I ask the RIAA and the copyright lovers what are my options? Please don't offer LPs or cassettes either.
On Limewire, the RIAA and other powers that be are now 'seeding' the message "Can You Afford $0.09 For Music?" - it appears during most keyword searches and obviously they have simply compiled a list of artists, songs, albums and/or keywords so this little nag shows up frequently posing as a music file. My response is, yes, I can afford 9 cents - do you want to sell me a song for that price? Deal!
Sure they will sell it to you but it will have DRM all over it making it almost useless.
No kidding! Makes those songs $0.09...or even a quarter, make sure whole catalogs are available and they'll see hundreds of my $$$$$!
There is a real point. I got a collection of "The Mystic Knights of the Oingo Boing" which is simply not available at all, anywhere, except maybe second hand on album if you can find even one of them. There is no other option except file sharing to get them. However, I doubt that the industry is looking for people who have out of print and unavailable music.
