My Question or Issue:

When I click on the plus button to adjust what playlist(s) a song is saved in, I am able to complete my changes but very frequently the changes are not saved or applied to the song. This is a newer issue, now that there is no "save changes" button to click on. I have many playlists categorized by time & genre, so many of my songs go in more than one playlist, which has suddenly become an issue with this update. In addition, when I am adding a song to other playlists, I am unable to remove the song from a playlist at the same time when I used to be able to do all of this with one step. Now the only way to remove a song is to use specifically the "remove from this playlist" button.

Ok. The bug where songs are not saved is fixed. But, still a bad experience ! I use folders to sort my playlists. When a song is added to a playlist that is in a folder, it dont show as before on top of the menu. I have to enter in my folders to see, on top of them, the playlist(s) where the song was added. In the old UI, the menu showed all playlists where the song was added, even if the playlists are part of a folder.

I really dont understand why your devs has replaced the old UI for this sh... !
