all my songs are still in my play list but I can't play them I can see them but the letters are not black they are a little invisible gray if you know what I mean.
Please help me to find out how the work again.
Are they songs you downloaded to your mobile (they have the green symbol against them) or are these songs you would normally stream?
Could you provide a bit more information:
Phone operating system and version
Link to the playlist
Do you still get this with spotify in online mode?
Did your premium subscription expire?
It's sounding like the files are on the phone but Spotify isn't seeing them. As far as I know you have to sync them through Spotify in order for them to show up. =/
