I can't see myself actually listening to that outside of the game, though.
I don't just want to be another stick in the mud, but I have to agree. I really like a lot of chiptune music, but Anamanaguchi doesn't do it for me. I tried to listen to their stuff and even saw them at Pax East, I don't know why, but their just missing that appeal.
To be fair, the stuff works well in game.
