Greyed out and unavailable tracks in playlist

[booztarsd]

I have a playlist with 140 songs, now around 90% of them are greyed out and it says Unknown album.

This happens in my phone and on the desktop app as well the issue is that if I search a specific song it's available on Spotify but not on my playlist.

The only workaround I have found is delete the track from the playlist, search for it againand re-add that track to the playlist (wich is quite annoying)

Any thoughts?

Were you connected to wifi? If you don't have wifi and are not premium you'll not be able to listen to those songs.
