Thanks. I do wish I had a library of moaning and crunching sounds, however, to accompany any transformation video I create. As has been said, sound is half of audio/video. I am not a foley artist, however, and I don't know where to go to get a library of sound effects. So, just so that it doesn't play in silence, I try to choose appropriate music to go with the video.
I chose Bad Moon Rising because it was showcased in American Werewolf in London and I chose
the Rasputina cover of the song because, well, y'know. And I chose
Wolf Moon by Type O Negative for the credits as an homage, kinda, to the end credits song/sequence in Howling II (no, I'm not going to link to that).
