Ha ha... nice finds!
The first one I had seen before, it's an interview/music video I did 10 years ago for some Danish TV station. I don't know where the person uploading got it from, but it's fun to see again.
The second, I had not seen before. It's a nice video and indeed it uses my music, but it's a little problematic in that I have not given permission for its use, but since it's just a short clip - less than 1 minute - it may fall under fair use rights or something like that.
Anyhow, in general I personally think it's great when people use my music in various projects (as long as they remember to credit me) and most often allow it, if it's within my rights to grant the use.
