The music player is located at the bottom of your browser. You can play, shuffle, repeat, sort or search for specific songs.
You can minimize the player to the bottom of the screen by clicking on the "show/ hide playlist" button or hide it entirely with the "X" button on the top (it will still will be accessible).
You can "pop-out" the player if you want to go to other websites and keep the music playing. Enjoy it all day if you want!
