My Question or Issue
Tracks greyed out that ARE available on Spotify. Almost certain this is happening to all tracks imported from iTunes, they're losing their link to the Spotify track. Details below.
I have a lot of playlists. At least one of them, with about 60 songs, has had every song turned grey, except 3 tracks.
The help here suggests that it's a licensing issue, that the songs have become unavailable in my region. I can confirm that it is not correct, the songs I've checked are nearly all available / licensed in my region when I search for them.
But - Spotify if you're listening - I think I know what's happening:
