Music On Demand free for XL customers

Virgin Media customers on the XL TV package now get the Music On Demand section for free. Press On Demand on your remote and go into Music On Demand for tonnes of free music tracks. They haven’t updated the page on the Virgin Media site yet though, so I’m still a bit wary whether this is actually free yet (although, when going into Music On Demand on screen it does bring up a message saying it is free on XL).
