This is easily my favorite song over the last month. I've listened to this at least 5x/day for over a month straight (not sure if I've ever listened to a song this much for so long).
Their song "Sorry" is also great.
Love how in Japanese rap they often sound like they're trolling, or mimicking a foreign accent (eg. what my Japanese sounds like). Not sure why they do that, but I find it hilarious, and it kinda makes me want to become a Japanese rapper.
