I think its rude for people to know what music other people like.
I refuse anyone to know what songs I like, and I don't want to know what kind of music other people listen to. When other people are in my car, I refuse to play music, or play music with the windows down. Also if someone chooses music for other people to listen to, or plays music loud enough for other people to hear, I think this person is a selfish arrogant douche. I don't listen to weird music, but I refuse to let anyone know what I like, IIN?
