Next to R&B, Videogame Music is one of my favorite genres. ^_^
In fact right now I'm listening to the
Star Ocean OST I don't know exactly what J-Pop is sorry, I just like the music, it's so soothing. I also don't know many artists outside of video games but I would like to. Importing is difficult for me.
Anyway some of my favorite vocals would be:
Simple and Clean(Remix too)
Pain (xenosaga)
Spirit (Xenosaga)
Eyes on Me (FFVIII)
1000 Words (FFX-2)
Suteki Da Ne (FFX)
and Fragments of a Dream (Crono Cross)
and just favorite songs without vocals would be:
Dream of the Shore (Crono Cross I love this one! ^^)
Blue Fields (FFVIII)
Sprouting (FFX)
and too many more to list >_<
It's hard to find others who are interested in this music, especialy your own bf so rate up to you!
