Looping PLAY statments in background of a game

[moochthemonkey]

How do I loop a PLAY statment continulously in the background? I just want to include a battle theme that is looped but I can't get it to work. I've used various thing, such as "MB" in the commandstring X + Varptr$ and even a similar example to the help files ON PLAY example but I can't see to get the game's music to keep on playing unless if I trigger something, like getting attacked by an enemy. Can anyone show me a good(hopefully simple) example to get this to work? Thanks
