Motorhead frontman Lemmy has hit out at record industry bosses for taking so long to adapt to the idea of selling music online.

The Ace Of Spades rocker insists the music business deserves its current sales slump - because executives have had years to figure out how to best promote music on the internet.

He tells Metal Edge magazine: "It’s killing itself, isn’t it? I mean, they (record companies) are too dumb to realise. I mean, it was f**king years ago that this started, and they just carried on doing what they were doing, blind to any advice, blind to any sort of evidence.

"They just kept on overcharging and kept on f**king people over, and now the chickens are coming home, you know? I think they’re all gonna be out of business in 10 years."
