Max Key hits out at The Spinoff over parody song

Former Prime Minister John Key's son Max has lashed out at The Spinoff website over a parody song it published mocking his threat to rapper Eminem.

The 22-year-old aspiring DJ announced on social media he'd release a diss track about the 'Kill You' rapper after the National Party was ordered to pay $600,000 to Eight Mile Style over a copyright dispute.

Max, an avid YouTube enthusiast, has published a video in which he watches the Spinoff's parody response, during which he looks increasingly unhappy.

"That is hands-down probably the worst thing I have ever heard in my life," the former boyfriend of beauty pageant runner-up Amelia Finlayson says when the song concludes, slamming his laptop shut.

"[The Spinoff] ridicules me a lot and basically pulls apart everything I've done. In their defence, I've probably deserved a lot of what they did. Some of it's pretty funny, I will give them credit. Some of the stuff I think they have taken too far, however that is the media."

As for an actual musical attack on Eminem, Max's original social media post stated he'd record a diss track if it reached 10,000 likes - which it has.

"Here we are, 10,100 likes later... I've done some dumb shit in the past and this is probably number one," says Max in the video, while wearing a pink bandanna tied around his head.

"I'm not claiming to be more talented [than Eminem] and have the utmost respect for him."

He doesn't give a timeline of when his new song can be expected, however.
