I don't know whether anyone would be interested since I'm just a random person haha, but I want to start doing this for myself even without posting it. But since I'd be doing it, I thought I might as well post it.

However, I couldn't find a suitable community. There's !japanesemusic@feddit.de, but they have some rules that would conflict with what I would post. "Title of music posts should contain "Artist - Title" in Romaji, optionally additional tags like [year] [genre]", which doesn't work if the post would contain multiple songs. Also "Do not submit more than one link by the same artist per day", since it's highly likely at least one artist will show up with more than 1 song in any given month.

I found some other Japanese Music related communities too, but they're genre-specific, like City Pop.

Thanks for any help, but if there's no such community, that's also fine!
