I think they just assume finding their own taste in music is hard so they don't bother and just listen to whatever is on the radio.
My girlfriend is 18 and still listens to Justin Beiber, One Direction, Ed Sheeran, etc. She's perfect but music is just something not worth getting into with her.
>Why do so many /mu/tants like the same music
Because you brainwash people with your charts and are all deluded fucks
I feel like they generally care more about the aesthetic or crowd related to the music that they listen to.
You can say the same thing about many people on /mu/, but it's a different aesthetic.
I think a lot of them just don't give a shit.
My gf doesn't have taste at all. The first time I asked her what she liked she hesitated for about a minute and finally answered "the Beatles?"
She just doesn't care about music, and never listens to it for any reason other than background noise. I'd argue that most grills never develop taste just because they honestly don't even care about music.
The same can be said for men, though. People are just plebs.
Most people just don't have that much of an interest in music. This isn't restricted to girls.
But that stuff's actually decent, femtard.
To be honest anon, I don't think your gf is like most girls...or most people. There's a small part of the population that views music like that. Not saying it's a bad thing but every now and then you'll meet someone like that.
