My Question or Issue

So. I'm trying to fix my fathers Spotify. Way back he had his entire music collections in ITunes. Some time ago i spent ages finding these 3000 songs on Spotify and making One playlist out of it (that's how he prefers it - don't ask me why..)

however, this playlist Cannot be played anymore for some reason (Song unavailable) - but basically every single song can be found individually and plays without trouble.

So, every song can be played, but not a single of these same songs can be played from the playlist. 

I have tried clearing the cache, relogging  reinstalled the app and everything else that came to mind.

I even shared the playlist to my own spotify user, but the problem persists here.
