[REQUEST]recommendations on some Jpop/Jrock male artists/bands?

[Chiharo]

Thanks a lot!
I'll tell you what I think after I DL and listen to the songs

EDIT: I really liked BRILLIANT!At first I thought that this kind of music is not my style,but while
I was re-listening to the songs,I really became to like them!cocoon was good,but not as BRILLIANT.
I'm gonna find some torrents that contain their best songs or something.

Thank you for links!
