Radish and vegetables have different tastes, and one person's hobbies are different. Knowing music doesn't make any difference. Knowing hiphop doesn't necessarily mean knowing music.
most of the reasons why you are so sad are not that you are sad because you don't know music. It's the person who said this, probably the person you like. So you will be so indifferent to what she says.
and when she said this, the implication was "we don't have the same language"! !
If you are really not interested in music, you don't have to learn it for her. The result must be that she can't see your advantages, and all she sees is your shortcomings that you agree with her.
So the point is to make her fall in love with you, let her know your hobbies (not to mention reading, surfing the Internet and chatting), and have her own special interests, such as tennis and sports. Have a more technical hobby.
