Violence? Drama? Isn't that what everyone likes? At least in entertainment.
I've been unfortunate enough to seek out Russian gangster rap on Youtube, but I've never heard Japanese rap before. So thank you very much for that. I'll admit that the most Japanese I've experienced has been in a miniseries (Shogun, The Pacific), the Battle Royale movies, and one of my favorite guitarists moving there (from the U.S.).
