I know the reason why some musics are greyed out on spotify, but I was wondering if there was anyway to find an alternative music for each of them.

I explain: I added at some point 'jealous guy' from John Lennon, and the music I added is now not available anymore, but when I search on spotify 'Jealous guy John Lennon', I see the music is available but with the title 'Jealous guy - Remastered 2010'.

So the only option that I see is for me to delete the greyed song in my playlist and add the available one. The thing is I have over 2000 songs in my playlist, and it could take me a very long time.

Is there a way to automate this?

And is there a way to show only the unavailable songs on spotify?
