This will seriously impact the community of music video creators, of which I consider myself one.
I do agree that music artists should be paid for their hard work, but if the animator doesn't load it up with flash ads and doesn't make any money off his/her own hard work, how can anyone complain? I also agree that the audio portal contains hundreds of purely talented individuals, but sometimes there is a limit to free talent; if a person is talented enough, they'll want to get paid for it and won't give it away for free.
I guess the only option is to seek permission for every music video I ever do, like I did for my current project I'm working on (slowly). I got the permission for the music, but now I'm worried because I'm using loose versions of copyrighted characters in the animation. Here's hoping I can call in parody. *fingers crossed*
