Confusion with music genres listed in "genres.json"

[polyarik]

I noticed that the genres.json file located in apps/core/assets/ doesn't include all the music genres out there.
Specifically, I couldn't find "City Pop" in the list. I was wondering if you plan to expand the list in the future or if you're sticking to a specific set of genres.

Also, some of the genres are listed multiple times but in slightly different spelling formats.
(e.g.: Post-Disco / Post Disco, Synthpunk / Synth Punk)
I'm not sure if this is intended or if it's an issue that needs to be addressed.

The file was sourced from an npm package and modified slightly. It is mostly used for title filtering, so it should be good enough. Different spelling is actually a good thing there.

Would you like me to add any music genres listed here that are not currently present in the genres.json file?

Additionally, I could sort the list alphabetically for easier reference :)
