_ViViD - Dear
_UVERworld - Revolve
_Damijaw - Daamii Shiro no Kyuuketsu Akuma ga Aishita Maria
_Mejibray - Apocalypse
J-Rock:

I honestly could go on, but I'm lazy. These are just what I'm into right now (That I can remember). I'm not too big into JPop and I'm falling out of interest with Vocaloids... *Laughs*
