Since some of you guys are mentioning Japanese bands I'm gonna add in my favorite ones as well. I kind of put japanese music on a different level then my other favorite bands.
I usually do too, but to me, music's music. Since OP didn't specify what kind of bands, I figured all was fair.
Also, I love Megumi Hayashibara. Round Table and Dreams Come True are pretty cool too.
