Reggae’s ‘Mr Boombastic’, Shaggy, has bags of advice for a more peaceful world.

And while it’s quite simple, sometimes those are the ideas that change everything.

It’s whether or not the barbaric Islamists of ISIL will listen that will make all the difference.

• Khaled Sharrouf’s daughter ‘mocks Australia’
• Opportourism: the top global deals with a catch

“ISIS can go f**k themselves. That’s some crazy sh*t what they’re doing,” he told the Miami New Times.

“It’s horrible, man. I can’t see… I don’t get that much hate. I just don’t get that level of evil. I can’t understand it.”

Islamic State, you know what to do.

Here is a solution that Shaggy wants these warriors in the desert to take up.

“They need to bag some Jamaican weed and distribute it amongst ISIS. I guarantee there won’t be any more wars out there,” he said.

“High people don’t want to kill nothing; they want to love.

“Man, it’ll put them in a vibe. And throw some Bob Marley up in there and there’ll be peace.

“Some of these world leaders need to be stoners though, really.”

And while they’re putting down their Kalashnikovs and packing away the rockets, they’ll have one soundtrack.

“If you’re able to cut a man’s head off, you’re sick. But right, music evokes emotion. So if they’re listening to Shaggy music or reggae music, they’re not going to want to cut somebody’s head off,” he said.

“There’re two thing you want to do when you listen to reggae: You get somebody pregnant, or you’re f**king high.”
