I've heard some music that I know was on the show on a different hunting video as well. Can't remember which show/video. I enjoy the music however.
Copyright free music or part of a sound effects/song program they purchased no doubt. No promise of no one else using a song you choose unless it is a custom made one.
I'm sure it's from one of the same royalty free audio packages that the music was pulled from. I know they have one of the audio packs from Video Copilot. Can't remember which on e the main theme is from though.
