My Question or Issue

Can someone point me to a guideline of what from Spotify on my android phone is also available for me on Android Auto?  Really just want to know what I can expect to be playable in my car so I can organize things on my phone to be available as it always seems to be a **bleep** shoot.  Or confirm from the list below...

- downloaded albums, playlists, podcasts

- "Liked" albums

- Playlists

- Local files

My car Device do not show local files although the permission in enable in app setting.
