Who Me Too'd this topic

Hello,

I'm currently working on a website to sort tracks by genre.

I've accepted that I have to use the genres the artist is categorized as. (I wonder why they don't offer it at track level, some artists have songs that have different genres. Apple music does it 👀)

But my problem is that those genres are too specific. I wish that there was a way to just get the umbrella genre instead of a sub genre.

For example Kendrick Lamer 
[ "conscious hip hop", "hip hop", "rap", "west coast rap" ] -> Rap.

But I'm sure that I will never be able to get something like that from the api so I was wondering if there is a list with all the genres that exists on Spotify? (and not just the genre seeds)
