I was just wondering as you are from UK it wouldn't be possible to have a shop on there. MySpace' official partner is snocap and they only provide service to US residents at the mo.
But its a third party player...hope they don't delete your profile for violation of their service terms...not sure what their stance on that is since everyone just sterted to put their "beatport players" up there.
Usually they didn't allow people to sell things directly from the page.
