Dio recently passed away, and all of a sudden he is more popular than ever. Why would he be more popular? Because the fucking scum sucking record companies see his death as a marketing device. They think of it as a double-bonus. He is dead, so they don't have to give him a dime of the profits. If he was so kick-ass, they would have marketed him before his death. But they didn't. Two months before his death, they didn't market him at all.
They do this with every artist that dies too. MJ, Justin Beiber, all of them. I know JB isn't dead, but we can all hope right?
