I got so sick of the same type of music. I got to the point where I stopped listening to music for the most part, though I missed music. Then I found House music, dance, trance, trip hop, ambient and dubstep. It was like a breathe of fresh air.
I still have friends who ONLY listen to alternative and rock. I see old men who still only listen to the music on 99.7.
Personally, I don't want to go through life without trying new things and being open to their awesomeness. It keeps things from getting stale. I hope I'm not the old person saying, "the things these kids listen to today is total crap" because in reality it's typically not, it's just different from what they are use to.
