If anyone seeds licensed content for free, you might consider him a rebel or fighter for information freedom, but if he takes money for seeding licensed content created by others, he is nothing more than a thief, who sells the stuff he stole...
It will be used by artists, the ones who produce will sell their stuff, not the thiefs.
Imagine how many micro producers, like hobby DJ's and other small entrepreneurs could sell their stuff there.
Whereas big record companties dont accept them.
