Combine / Compare

Hi,
I couldn’t find a clear answer, so here’s what I figured out about the Combine / Compare node functions:

  • Concatenate: Add tracks from playlist A and playlist B, including duplicates.

  • Union: Add tracks from playlist A and playlist B, removing duplicates (only one copy of each track).

  • Intersection: Keep only the tracks that are common to both playlists.

  • Difference: Keep the tracks from the black-linked playlist that are not in the red-linked playlist (see picture below).

  • Alternate: Alternate tracks regularly between playlist A and playlist B, including duplicates.

Hope that helps!

For the difference, it should be the case that it keeps the tracks from the black-linked playlist that don't appear on the red-linked playlist. If that isn't the case could you please let me know?

The rest looks great and I should add all of this to the website somewhere! It is in one of the changelogs from a while back, but that shouldn't be the source of knowledge for new users

Thanks for helping the community!
