Should I post in the [Category] Comm or should I make a [Sub-Category] Comm and post there instead? (Or do I do both?)

e.g: c/Music...

I wanna make a c/ChineseMusic... cuz it's kinda weird to post in c/Music where its mostly English/Western music... I don't wanna feel kinda obnoxious and feel like I'm "invading" a space... (and c/Chinese is for language learning, doesn't feel like I should be going there to spam Youtube links lol)

(I've been finding a bunch of Mandarin songs on Youtube and I feel like sharing... or I guess it could also serve as a sort of "bookmark" for me lol)
