Ive been listening Melodic DM that is the best music for me ever ..
country music and classic
Pop, soft rock, country and sometimes blues
so you're generally dealing with Asian languages ..ok:)
Used to listen to Black Metal. But quit, it's a way too destructive. And almost no use for the language learning, since it's very difficult to recognize words in all those screams and moans=) But that time was great too, in its own unique fashion.
Now I mainly listen to Japanese music or some old rock bands...
yeap..Metal)
