Why don't we tire of music?

Music offers the right combination of providing structure while granting enough freedom to form our own interpretations of meaning. These interpretations resonate at a very base emotional level - something modern society tells us to "keep a lid on", in almost every other context. And our interpretations can change from day-to-day, or over time. That prevents boredom. Good music also hits the right centers of our brain to release dopamine so we feel then need to come back for more.

Watching a movies, you’re too passive of an observer. Once you reach the end, 99% of movies lose all rewatch value. Once I know what happened, I don’t need to watch it again. I can count on my hands (out of thousands) the shows / movies that have any rewatch value, and even then the rewatches have to be spaced out (at least a year).

This has become a silly non-argument.  Everyone is different.

Maybe non professional musicians don't...

Most movies I only watch once. I watched Brazil twice. I watched A Clockwork Orange 3 or 4 times.

I do get tired of the same music.  There are bands that I won't even play anymore and even change the radio station when anything from them comes on.  There are also songs that I won't listen to for years at a time and then suddenly get a craving for to relieve some old memory.  In my experience, the longer it takes me to like a song the longer it takes me to get tired of it. This goes for all genres.
