you tube have dealt differently with copywrite issues on covers of songs I've put on there, they either don't pick them up, or the original songwriter isn't bothered, Daydream Believer was taken down (with a warning), when I uploaded a version of Mrs Robinson, it said they'd detected that the song was a cover and we wouldn't get any royalties for it, a couple of other covers I uploaded at the same time went through with no problems, go figure
