In the clip you posted you are singing a traditional, presumably Public Domain (PD) song. If he was posting one of your originals he would certainly have broken your right to copy for the original composition.

I suspect you have a complaint about someone using your recording, even of a PD song - but that may depend upon how you publish it and the local laws governing such things in your area. He almost certainly has problem publishing a photo of your album cover - without permission.

I have had this sort of thing happen to me pretty often - usually film from live shows, sometimes of me performing original songs, sometimes others. Most of the time, they post the clip then send me a link and ask for my permission!

I have always said YES because they mean well and of course every little bit of promo helps, although some of these clips are ones that I wouldn't have put up (bad hair day, bad sound, too much sun, not enough light, etc etc).
