This man should never, ever be president. Ever. Besides being a blustering, unfunny, Owen Wilson-left-out-in-the-sun, Donald Trump is a complete shark – and I mean that in the worst way possible. Have you seen the way he treated people, or rather ordered them to be treated, when he came to Scotland and bulldozed the place to make way for a golf course? That's presidential material right there. What a guy. And now he's showing some real leadership skills with some childish tit-for-tat tweeting.

When he announced that he'd be running as a candidate he walked out to Neil Young's 'Rockin' in the Free World' – without permission, which something that Young himself didn't take kindly to. Naturally Trump took to Twitter and did his best moaning:

The "audio deal" refers to Neil Young looking for Pono investors. Regardless of that, this is a different transaction; just because you give money to somebody one time it doesn't then warrant your using their music without permission. Also saying it was "just one of 10 songs" doesn't make it any better – in fact, it makes it worse: I doubt Trump bothered asking permission to use the other 9 songs.

But Young is not much better. He took to Facebook to say "I make music for people not for candidates" – despite previously endorsing Senator Bernie Sanders, who used 'Rockin' in the Free World' at a recent rally.
