It's just... very, very biased.
Don't get me wrong - although I'm a PS3 owner, I like both consoles (let's be honest, right, there's hardly any difference between the 360 and PS3 when it comes right down to it). This was irritating to listen to, though, in a sort of "Do you have any real point to make?" sense. Most of it really was just your opinion in a song with no for-PS3 facts taken into consideration.
The only thing you said that may be taken from facts & figures was the thing about the PS3 being more expensive - which is contridicted by the fact that, depending on how long you have a 360 & have it online, the price for a 360 will eventually exeed it's original price.
And yes, I did read the "THIS ISNT TO DO WITH MY OPINION!!!" part. Personally, I don't believe that one bit. On the off chance that it is true, however, think of this as directed at the "Anti-PS3, XBox-orgy" people who watched this.
