Since Spotify doesn't have a unified queue synced between devices I use a "later" folder to add albums and songs to playlists that I want to come back and listen to later. I mostly use this for albums.
It's really easy to create an album playlist. Click the album's ellipses, add to playlist, click the plus, accept the playlist title. When you drill down into a folder, though, the plus sign disappears. You have to click edit, plus sign, and fill in a playlist name manually.
When i want to save a record as a playlist Spotify suggest that the playlistname will be the same as the artist - recordname. But if i want to do the same thing, but saving a record as a playlist in a folder i dont get a namesuggestion. So to get around this i have to save it to the root of my foldersystem and then move it. Would be happy if this would get sorted out.
