I feel it depends a lot more on how many songs you’d be posting compared to the other activity in c/music.

I’d say post some in the main comm, and if you really want to share a boatload with of songs (like multiple everyday for the foreseeable future) create your own community and cross post a select few to the main category.

It might be nice to have a community a little broader than just Chinese music, like for non western music or maybe East Asian music.

IMO doing both is probably fine

Depends on the population number and temperance of the community. In your example, the Mandarin songs would likely be ignored. However, there’s a chicane somebody checks one out. Whereas if you made a comm for Mandarin music, those same users wouldn’t sub to it Abe would never see it.

Currently listening to Japanese music. I’m one of the ones who would give it a chance. I used to listen to a Chinese album I Shazamed in a Chinese restaurant once. I’ve long since forgotten what it was, but it was very pleasant to listen to, so I may try to find it again.

If they’re not too many songs I’d just post in c/music. There’s also !nonenglishmusic@piefed.social where they’ll probably appreciate it more, just check the rules because they require a specific format.

I split up my communities pretty fine-grained: !reign_fc@lemmy.world for my club, !nwsl@lemmy.world for my league, !ussoccer@lemmy.world for my international side, etc. At the time, we thought the glorious revolution was just days away, and we’d have a gajillion users and we needed to be ready. In hindsight, I regret this decision and wish I had just created a single overarching woso community for everything — like !womenshockey@reddthat.com. There just aren’t a lot of users, and having a fewer, more broadly focused communities allow for larger user bases that interact with each other more often. So, if it were me, I’d post to c/music and try my best to feel comfortable taking up space.

It doesn’t hurt to make a sub-category community, but please also post to c/Music. I certainly hope that on Lemmy we can stop defaulting to the majority language and culture.
