Artist field on saved tracks does not actually return gerne
I understand that Spotify only has genres for artists, not for individual tracks. However, in the documentation and example of the Get User's Saved Tracks endpoint it states that the generes are returned for every artist for every saved track.

It also states this in the example response:

This however is a not the case and has not been the case for some time given these posts:

This is very unfortunate because this means if you want to know the genre of saved tracks you have to do 2x the request. For every batch of saved tracks you request you also have to request the artists seperatly again to actually get the genre. This means double the amount of bandwidth.
It would be so much better if the genre data was just returned in artists field of the saved tracks like the (documentation states it does) instead of having to request genre seperatly.
If this is absolutly not possible then please update the documentation to avoid confusion in the future.
