I went through a phase of listening to 'emo' music. I assume you mean this because you said emotional music lol. I don't think music tells everything about a person by any means. It's good to have music you can relate to.
When my brother makes fun of me because I do things that are stupid to him. He makes me feel like ♥♥♥♥ for no reason. "Oh my God! I can't believe you're actually listening to that kind of music! Are you ♥♥♥♥ing gay or something?"
He's really mean about it. It's like, "What the hell did I do to you?" That's what I think inside my head.
The one time I listen to music without the headphones on, and he just has to tell me his opinion! It's like "I'm sorry that I like to listen to different types of music, unlike you! I'm sorry that I like this song! I'm sorry that 'I'm a sissy!' just because I listen to emotional music!"
You want to know what I want to actually say to him sometimes?
