FYI, they just released a new song Girl's Talk.
Through YouTube's very surface-oriented "similar" music algorithm, HANNABIE. came up. Yeah, it was after listening to Baby Metal, and yeah, they are metal-ish, all female, and Japanese. There are quite a number of bands like that and out of the ones thrown my way, these folks grabbed my attention. Many consider them metalcore but also have punk and nu-metal elements with the occasional hip-hop and electronica mixed in.
They are still on my playlists, but it's been long enough that they aren't on my trending list anymore.
