Guess it all depends what you like/want. For something heavy you could check out Austrian Death Machine or Mindless Self Indulgence. For some 8-bit you could look up Anamanaguchi or Unicorn Kid (or listen to chiptune on Pandora for some more ideas). If you want funny and funky there's Here Comes the Mummies or for funny and wrong you could go with Stephen Lynch. If you want just a bit odd there's Pogo. Hope there's a few new things in there for you.
Chiptunes and Here Come the Mummies? Your musical tastes are broad yet discerning! I will plug my wife's podcast http://5songset.net/, which has featured both of those groups, among many others.
