I would say overall music is better, since it is quick and easy entertainment. When you watch a movie you have to be able to commit at least an hour and a half usually, while you can listen to a song in three minutes.
Their is more good music than good movies so I'll go for music. It is easier to just listen to while doing something else. Movies require your full attention.
It really depends on the situation, but I listen to more music than watch movies so I say music. Besides you can do other stuff while listining to music.
