How to make a loading screen?

Hello all, I have a prototype made by a friend of mine, and with all simple prototypes I have images and music that need to be loaded.

The images load pretty fast (in fact, they do it instantly) but the music does not. Most of the time (specialy in the Windows version of Chrome) I end up playing the game, and then only after a long while the music starts playing. How can I avoid this so the music and the game start at the same time?

 

I though that adding a loading screen could fix the problem, but after googling I could not find an example on how to do it using Phaser. Can someone help me do it or give me tips please?

<html>    <head>        <script src="Phaser.js"></script>    </head>    <body>    <script>                       	// get users screen size			var w = window,   				d = document,    			e = d.documentElement,   				g = d.getElementsByTagName('body')[0],    			x = w.innerWidth || e.clientWidth || g.clientWidth,    			y = w.innerHeight|| e.clientHeight|| g.clientHeight;            // get users screen size            //winW = document.body.offsetWidth;            //winH = document.body.offsetHeight;                        // choose a random image for game background            var backgrounds = [                                "images/brown & purple.jpg","images/green & black.jpg",                                 "images/multi.jpg", "images/simple.jpg","images/grey.jpg"                                             ],                background = backgrounds[Math.floor(Math.random() * backgrounds.length)];                              (function () {                            var game = new Phaser.Game(x, y, Phaser.CANVAS, '', { preload: preload, create: create, update:update}); //w, h                                               function preload() {                                        // load and name the game assets                    game.load.image('player',       'images/player1_01.png');

Even with a game state the issue here is the audio file decoding, not the way the code is structured. But as we've both said, look at the template because it explains how to pause for the audio to be ready first.

maybe we could do like this http://gametest.mobi/phaser/examples/_site/view_full.html?d=games&f=tanks.js&t=tanks and use what rich suggested.

we could add a logo(or whatever else) in front of the game screen and pause while the audio loads ,then when the audio has finished loading we could kill the logo and start the game.
