JPain Vibes / Study (Playlist)
I was first introduced to Japanese music through anime (duh) OPs. I mean, there are the EDs but I don't typically like them (there are a few exceptions though, like mawari mawaru [sasamonaly] and the few ASOBO DOUMEI EDs). I have much more songs I listen to in JP than EN, partially because JP songs are normally much more melodic and varied, they're pleasing to the ears. Also, Japanese as a language is very soothing, it's so addicting! A lot of the music I found when I first started listening to JP music was through osu! and Beat Saber, funnily enough... nowadays I just use YT recommendations and radios of artist/songs I like.
The two main types of Japanese music I listen to are:
I do occasionally listen to J-Rock but im more into pop-rock anyways.
