How does it work better for you? To me it's annoying, I cannot easily move folders around anymore, nor move playlists into folders if I'm not using the desktop app.
Also, the + (former ♥️ button) is the worst offender to me. I used to use the button to add a music to my big "liked" default list, the one that is more permanent, and the three dots to add it to a playlist, which are more fluid. So playlists come and go, and not every song on a playlist is the one i want on my definitive pool of "always wanted" songs.
Then someone at Spotify decided to say "fuck you users", and merged the + and three dots, making it harder to know if a song is already in my main "liked" list.
Say I have a playlist I created, the + button is now a ✅ button. It tells me the song is saved somewhere. I have to tap it to see where, which 1. is completely unintuitive, because tapping a check button would create me the expectation of uncheking it, but it instead shows me a list of playlists! What in the freaking hell? This is decades of UI convention thrown out the windows for a really bad concept.
And 2, being checked doesn't mean it's my favorite song, just that it is saved on some playlist. It's a mistery, which is only solved by tapping the schizophrenic +/✅ button, instead of simply saying to me "yep, you liked this song".
