mostly Nu Metal with stuff like Disturbed, Drowning Pool, I love techno if you are into that, also MSI for being funny and psycho at the same time lol.

there are some good Jpop singers to check out

puffy ami yumi is pretty good, so is yuki kajiura, as well as Utada Hikaru who does the simple and clean song from KH shes really good at singing other things to

I like a variety of musics to be honest as long as its not rap or country. thats a good start check out nu metal in general if you are into it its awesome!
