##Available methods

###play

The first method to call after instanciation (Calling other ones will do nothing ;) ). It will start playing if called the first time and resume if the music was paused before. You can specify the volume and the number of time the music will be played with the volume and loop options

    player.play({volume: 50});
    player.play({volume: 50,
    			loop: 10});
