Playing Music and Sound Effects in a Windows 8 Metro Style App using HTML and JavaScript

I have recently been coding a Windows 8 Metro Style App using the new Windows 8 Release Preview bits and Visual Studio Express 2012 RC. The app is going to be a retro shooter that takes advantage of HTML5 Canvas for the main game engine and then several Windows 8 Metro Style App Features. What game would rock without Music and Sound Effects! So how do we add that functionality to a Metro Style App? For my game I decided to take two routes.
