About a month or so ago I was completely against the idea of Babymetal...But then their music clicked, I heard their second album, and I've been a fan since. This album, Metal Resistance, is nothing but a stroke of genius, some of the heaviest songs I've heard in quite some time (Sis. Anger, for example), mixed with some of the most interesting vocals I've heard used in metal makes for quite a strange experience. To listen to them you really do need to accept that as they're from Japan, some of their stuff is very cringy (and that's an understatement) but once you get past that, the music is absolutely brilliant and I would 100% recommend Metal Resistance if you haven't heard it already.
Their first album (self titled) is a bit more toward the Anime sounding side, which I'm not so much of a fan of, however I would recommend a listen to Headbanger and Megitsune as they have very nice moments. Otherwise that's not so much my cup of tea.
I've also been listening to a lot of Rammstein for the last few months, if you can get over the most popular songs (Du Hast, for example) and find the far more musically entertaining (Zwitter, Sonne, Ich Tu Dir Weh, etc) you will be blessed with some of the most satisfying metal out there, and I definitely recommend listening to them on shuffle to see what you like as each album has a very distinct sound
