Better than acting like you're a better person because you listen to some math rock group.
Idk what it means to have trash tastes, id like it if someone said that and then named the stuff they liked and I conformed it was trash lol. Id find it really endearing.
I have really eclectic tastes too, and I like my own taste in music, but I've also found a lot of people don't really like some of the music I get really into. I can't tolerate like 90% of popular music from the last 20 years or so, but I still like a lot of indie and experimental stuff.
