I am a local roots and blues musician and I recently had an 18 year old girl tell me at one of my shows that she loved my music - so she was going to burn my CD and give it to her friends - as if that was a good thing. Yes, I might get exposure and her friends will hear me, but it won't help me buy food or pay my mortgage. Her friends MIGHT tell their friends about my music, but it still doesn't help me survive financially until they actually spend money on my music.
I spend at least 50 hours a week trying to book shows, writing music, updating my website, promoting shows, traveling to gigs, rehearsing, doing accounting, etc.
It sounds to me like most people I hear commenting on this page have NO IDEA how much WORK it is to make a living doing music. It is a craft that I love and that requires years of patience and hard work. I'll be damned if I would let some idiot remixer who has no idea about the etiology of blues and roots music, denigrate the art by using it in a dance remix and not giving proper props to the original creator.
I guess the main point is that 'owning what you create' is an important civil right (aka a 'copyright'). It is a right that fosters the development of personal crafts.
There will always be a large business attempting to sell something with mass appeal - but the responsibility ultimately rests with the audience. I don't blame the RIAA, or Sony, etc... they make money off of stupid people. If the public wants good music, the public must demand it and support it.
