[FEATURE REQUEST] Per song visual indicator of save status

[jdmarshall90]

As a user, I want to be able to see at a glance if any given song is already saved to my saved tracks list. Whether I'm looking at a playlist, now playing, or an album view, it would be great to know if a song is already saved.

AFAIK the problem with this is that it would involve a lot of calls to the Spotify API, with the potential risk of getting the account suspended.

Probably not. Since we have the saved songs playlist, we'd only need to see if a given song is there.

Basically, it wouldn't be any expensive.
