Is it normal that the songs my girlfriend likes hurt my heart?

My (ex)girlfriend likes some cool music, but some of the things she listened too made my chest hurt. For example, I had never heard Black Veil Brides, but when I heard them after she mentioned them, my chest hurt like I found out a person had been hurt. I think it was because I thought of her feeling the way that music is, which is angst-y and depressed. But aside from that, other music makes my stomach hurt or gives me a weird feeling. Nirvana's Unplugged album has such odd guitar tones it makes me uncomfortable to listen to it, even though I like the songs themselves. Does anybody else get an uneasy feeling from certain music?
