Here's a script adapted from this blog post to download a file.

In SlimerJS it is possible to use response.body inside the onResourceReceived handler. However to prevent using too much memory it does not get anything by default. You have to first set page.captureContent to say what you want. You assign an array of regexes to page.captureContent to say which files to receive. The regex is applied to the mime-type. In the example code below I use /.*/ to mean "get everything". Using [/^image/.+$/] should just get images, etc.

var fs=require('fs');
var page = require('webpage').create();

fs.makeTree('contents');

page.captureContent = [ /.*/ ];

page.onResourceReceived = function(response) {

    if(response.stage!="end" || !response.bodySize)
    {
        return;
    }

    var matches = response.url.match(/[/]([^/]+)$/);
    var fname = "contents/"+matches[1];

    console.log("Saving "+response.bodySize+" bytes to "+fname);
    fs.write(fname,response.body);

    phantom.exit();
};

page.onResourceRequested = function(requestData, networkRequest) {
    //console.log('Request (#' + requestData.id + '): ' + JSON.stringify(requestData));
};

page.open("http://....mp3", function(){

});
