Good points on the copyright holders vs. artists regarding the royalties, and also the library aspect.
I was discussing the impact of file sharing with a friend last weekend, and the used CD system came up as one way where music was “shared” (in a way of thinking) without the artists directly benefitting. I wondered if the artists at least got increased sales numbers for the music charts from used CD sales.
Seems the only way to support a musician’s work, either directly or indirectly, is to buy new. Unless of course you go to a live show and/or buy merchandise.
Even if the musicians don’t own the copyrights (and from what I understand, most bands sign these away for recording deals), they are still paid something for these rights. I am sure it’s not in favor of the bands of course.
