Nice work here with all the additional functionality over the stock player, though the interface is very unintuitive and clunky. I mean, theres over a dozen steps you need to take just to play one album of music if you already have the "now playing" playlist populated.

1) Open Some player. 2) Open Library. 3) Open playlists. 4) Open "Now Playing". 5) Select All. 6) Remove selected. 7) Go to artists. 8) Select artist. 9) Select Album. 10) Select all tracks. 11) Add to "now playing" playlist. 12) Go to player 13) Press Play.

Also, having a "back" button that appears as part of the internal menu structure while simultaneously utilizing the app menu bar "back" button is...meh...especially since its neither apparent nor consistent throughout the app which back button your supposed to use at a given time. It's almost as if the whole interface was designed to be as cryptic and confusing as possible, which for me totally detracts from the additional functionality over the stock player. Seriously not trying to be negative, just saying that if it takes navigating 13 steps through a cryptic UI just to play a single album of music, there's some room for improvement there .
