Currently, as of 12:30pm on Nov 28, Saturday...I am unable to edit the track order in playlists. The icon associated with the procedure appears when I scroll over the tracks but it doesn't allow me to grab and drag the track like it's supposed to. I'm using safari 9.01 on a Macbook pro running El Capitan. Please address.

The way to do this has slightly changed. Please click on the small pen icon on the playlist, choose the "Tracks" tab, then edit the order from here and save.
