I posted this question on Apple Support, and though a few people indicated they had the same question, no one has come forth with a solution yet either, so I figured I'd ask this forum too. I'm running the latest version of OS X El Capitan as well as the latest version of iTunes. Since the update, playlists in the sidebar have no longer been arranging themselves alphabetically. Normally, when you create a new playlist, it automatically places itself in the list alphabetically--now newer playlists just show up at the bottom and there is no way to custom arrange them. Is this a glitch or a new feature or is just my computer? Anyone else notice this?
