What do you tell someone when they say something like you like rock whats wrong with you raps the best something that shows them to leave your music taste alone?

Answer 1

Well in that situation, remind them that modern rock came before modern rap, and in many ways, rap is defined as being not rock. Without rock, there would be no rap, as every new music phase is a rebellion against what was popular previously.

Alternatively, you could just politely say that, while some rap has its good qualities, you prefer rock because of its musical content, emphasizing the music instead of the spoken word.
