Menu and in-game music , how to

Hi

I wonder how to add music in the main menu

I guess i need to place the command here ?

function loadMainMenu()
{
// Startup the client with the Main menu...
Canvas.setContent( MainMenuGui );


// Make sure the audio initialized.
if($Audio::initFailed) {
MessageBoxOK("Audio Initialization Failed",
"The OpenAL audio system failed to initialize. " @
"You can get the most recent OpenAL drivers here.");
}

Canvas.setCursor("DefaultCursor");

///////////---> HERE
}

correct me if wrong

but my problem is what command should I use and do i need a datablock , etc
