Title: Compare playlists: how?
Post by: MarkCoutinho on April 07, 2023, 03:15:25 am

I want to make a comparison between two playlists so I can see if there is an overlap between the two.
I have searched and think I know that this can be done using ListEqual as an expression. So in my case it would be    listequal(Top 500 Jaren 70, Spotify nog niet)
But I have no idea how to "program" such an expression. Where should I start to set up such an expression?

Thanks in advance!

You could try using MC's split view and show one playlist on each side.  Not automated at all, but might help illuminate the common titles.

Thanks for your suggestion. I tried doing that, but I see no illumination of duplicate songs, even though they are in both lists. Should I do something extra apart from using Split View?

You can create a smartlist that shows tracks present in one list but not on the other, just add these 2 rules:
Playlists - is any - Top 500 Jaren 70
Playlists - is not any - Spotify nog niet

Or vice versa.

You can type the equivalent expression in the search/filter box as well. Select the "Top 500 Jaren 70" playlist, then type this to hide the tracks present in the other playlist:
-playlists="Spotify nog niet"

Thanks! In the end it's actually quite easy, although I probably didn't explain myself correctly, because 'Playlists - is not any - Spotify nog niet' has to be Playlists - is any - Spotify nog niet

That shows files that are in both lists (which I see now is what you wanted). You can have both variants, depending on your needs.
You're welcome.
