I like pigeons and seagulls. and rats are cute.

I wonder if the difference is between people who like music primarily because of the memories it evokes vs people who just like music for its own sake. I’m sure this is a gradient, with most people probably falling closer to the former category and those at the other end of the scale seek out new music.

Same. I’ll rarely put on music from my teen years (90s for me), but for the most part I’m listening to stuff released from the past 5-10 years, or older stuff I’ve recently discovered from before my time. There is great music (and shit) from every decade.
