this is more about why people listen to music. so many reasons!
ironically. nostalgically. to sing along to in a car. to jump about to in an empty room. to dance to in front of/with other people. to karaoke. because it was in that movie. because it's vedder playing a ukulele singing 'dream a little dream of me'. because "the sentiment was really nice". because it's good music. because it's so bad it's good.
...and all of these things are subjective!
