Have you tried the GazettE? They are pretty popular. I can name off a bunch right now lol. SuG is really good, but their older stuff is more bubbly and child-like compared to their new stuff though. SCREW is really good too. I love those guys. <3 There's also Reign as well, but Reign is fairly new... so you won't find a lot on them. Um... *thinks* That should at least give you a good starting point right there! I don't want to overwhelm you with a whole bunch of different bands because I know a loooooot. XD
