Before I was into kpop I listened mostly rock music, lot of alternative rock from USA/UK and some JROCK as well. Even tried out Visual Kei, but wasn't for me. Since then my taste has become more pop (maybe cause it's harder to find good rock music these days sad), but I still don't listen to mainstream pop outside of kpop. I have couple jpop artists I like, but apart from that I listen mostly subgenres of electronic. There is couple pop songs I like, but they pale in comparison how much I listen to other stuff.
