Working on player.js. I'm trying to get the music control buttons in the nag bar working. I'm getting an error when I click the play button (built into the navbar):

Uncaught TypeError: undefined is not a function player.js:42
playSong player.js:42
o.event.dispatch jquery-2.1.0.min.js:3
r.handle
Added in a settings button in the nav bar.
Fixed button sizing. Have to stop right now because I need to study.
