So #Plex has a "sonic adventure" feature that lets you put in two or more songs then it fills in a playlist which selects tracks of sonically similar values leading from song to song until you reach the target using tracks from your collection.
Here is a playlist it generated going from Phoenix by The Tear Garden to Lisztomania by Phoenix.
I would not have created this playlist on my own.
Also it is fun to see #fedi artists pop up in playlists based on sonic thumbprint.
