Any suggestions for a heavy metal song?

My boyfriend is very into heavy metal,(like Korn etc) Im not,not that I don't like it just not familiar with that type of music and bands,but i am having doubts about our relationship lately and id like to send him a a song via you tube to give him an idea what im feeling, It doesn't have to be a recent song,and it doesn't have to be relating to a relationship,like those having a bad day songs,but that it would be a heavy metal one Please any suggestions?
