Cheryl, my Video Production instructor, and I were talking about this the other night. I think that the "fair use" guidelines should be made a bit more clearer than they are now. Here's my beef with these copyright claims: We, as YouTube users, are NOT making money off our videos--no profits, not a dime. In fact, we are essentially advertising songs on YouTube so that people can legally download them from Amazon, iTunes, etc. The artists make the money because their fans enjoy their songs on YouTube videos, and they go to Amazon or whatever and legally buy them. This is why WMG loses money, because songs from their catalog get muted from a video, preventing loyal listeners from purchasing songs from their favorite acts--especially when most YouTube users give the proper credit to the artist who performed the particular song.
