I'm not really all that big on music that I would consider "entertainment", I prefer music/musicians I consider to be real art/artist. but depending on the mood will watch a movie that is either artsy or simply entertaining. so, I have to say movies are more entertaining, for me.
Tough call. It's visual vs. auditory, and both things are fairly primal to humans. Humans have probably always had some form of music and story telling. I'll vote for music just because, as you say, you can listen to it 12 hrs a day.
