She listens to Chris brown, and some gays i can't stand. She fucking hates all the rappers i listen to like Eminem, 2Pac (She even got mad once cause i was busy listening to him, instead of talking to her), 50Cent, she fucking hate Nate Dogg (these niggas she listen to use auto-tune, before auto-tune we had nate dogg!), i won't mention the rest like Biggie, rakim, Nas (Yeah, she hates violence she told me, ain't this a bullshit?), NWA.. etc
Honestly, I don't think that's a good reason to choose not to date a girl. I don't actually think you should ever reject a girl based on one little thing. She could be a great match for you, and you'd be giving her up for someone else, just based on the music she listens to.
Okay I completely understand this, music is a big part of everyone's lives. My boyfriend likes Kevin Gates and Drake but I like Stone Temple Pilots and Foo Fighters. If you really like this girl you gotta except y'all's differences. She's gotta except you and not judge your taste. If she refuses to comply then just tell her you're no longer interested or it just doesn't feel right.
