This is very cool and well done, but it doesn't really reimagine how Playlists work so much as how you manipulate them. Also these days I think people put less time into the specific order of a playlist and just use them as a folder to shuffle in.
What about tagging songs so you can make mix-and-match playlists for whatever your mood is at the moment instead of relying on the old and tired "folder" format every music player currently uses.
There is so much interesting functionality that Spotify or Apple Music could build and instead they stick with what is essentially "Finder for Music", the blandest and least functional approach possible. I struggle with how much money I give Spotify and how regularly disappointed I am with their lack of innovation or progress.
I'm curious, what did you identify as being the current problem for adding songs to a playlist? (3 dots + Add to playlist)
Also, did you know that the "add to queue" was a swipe right on any song?
PS: The video is a bit hard to follow because of the angle and the hands!
That's so cool, I really like the drag and drop functionality
