I know that there are accounts on MySpace for a ton of J-Rock bands (whether they're official or fanmade). Since most of the pages I've seen have pics and music on them, I'd figure I'd keep a list here because it's a great way to get into a new band. :D
Artists listed last name first. (Ex: Hamasaki Ayumi)
