Observed in iOS 8 (β 3) and iTunes/Mac (11.2.2 (3)?).
Both the iOS Music app and the iTunes app on OS X suffer from this bug: you can't order your playlists. No, I'm not talking about the songs in a playlist, but the playlists themselves. I'd like to have easier access to some of my more frequently used playlists, but they're unhelpfully ordered alphabetically:
Oddly enough, my "90's Music" smart playlist is at the top in iTunes, but at the bottom of my smart playlists on iOS. But nevermind that-- I want to order them manually.
Apple: please fix that.
