And there they are, 4:57pm PST. Video and Music apps have updates.
Change log is pretty minimal. From looking at the app it looks like the now playing now shows a "Up Next" song at the bottom. The list of playlists loads pretty fast but scrolling is still miserably slow... but you can finally scroll more than 100 songs in a playlist! Before it would stop at the 100th song and you'd have to wait for the next songs to load.
