The Music client for Mac is still an excellent music manager and player and beats Spotify by a mile despite how visibly much they've let it bitrot* since it was iTunes. It's a shame neither the mobile app nor the web client has anywhere near the capabilities.

* for example, what the fuck is that stupid unresizable header that takes up half the window with mostly empty space and doesn't scroll off the screen anymore if you set a playlist view to "as Songs"
