This battle has been going on for over 30 years now. Once the cassette became the standard over the archaic 8-track, it was easy to 'copy' the songs you liked from the vinyl LP.
You bet it is about the money going to the companies and not really the artists and the song writers, etc. I don't work in the industry but have heard the arguements for a long time. Hard to quote 1970's stuff here as the web wasn't around then. The same problem exists in the computer world with software applications and use. Who makes copies and gives the CD/DVD to a friend to use -- piracy there also. Same principle!
But I believe it is all about once you have legally purchased the material, you should be able to listen to it in any format that you have bought. After all, the RIAA has not sued the manufacturers for putting a record button on casette drives nor sued the manufacturers of writable CD/DVD devices yet so people can make copies of music, software, videos as needed in order to perserve those items for their personal use. I seem to remember that there was an implied lifetime use when purchased -- no one bought a limited license on any product.
I also like to hear my music mixed with other artists -- not just the Beatles, AC/DC, Hammer or whoever. Having them all on the same tape/MP3 seems to make the most sense to my tastes. That way I can listen to what I like when I want to, not when the radio station thinks I need to hear something.
And I buy the music if I like the group/artist. I don't buy it if I don't like the music. If they just put out garbage (highly technical term here) in order to comply with a contract, then they lose me as a listener/fan. I only liked certain periods of Elvis (Presley) not Costello (him also really). But I did like all that the Beatles did together and most of what they did separately. I didn't buy all of what Ringo did though. He needed more help from his friends.
So I have a mix of vinyl, CDs, tapes and an odd 8-track (that I can't play anymore) laying around. Can I sue the RIAA for storage of their artists material?
