Single song in a big playlist can't sync

[pjalle]

I have a playlist consisting of 45 songs.

1 of them is implemented from iTunes, the rest was available on Spotify.

The one implemented from iTunes plays fine from iTunes itself and I made it show up in my playlist on Spotify - It is greyed out however and if I try to play it says "Song Not Synced" - The song is on my iPhone though and it plays fine from iTunes and I can play it through spotify on my computer. 

Here is a screenshot from my phone:

Clicking the "..." symbol only gives me the option to either "Add to playlist" or "Add to queue".

Hey @pjalle. Welcome to the community. 

Its possible this track isn't a supported file type. Have you tried adding a different file type of the same track? 

You could also try removing it and adding it.
