Arctic Monkeys vs Pink Floyd

It seems to me that these two songs show an enormous resemblance. Judge it yourself, at least the first seconds of each.

I will not state who’s copying whom because I do not believe this is a case of plagiarism. Nothing, absolutely nothing in this life—and especially in music—is 100% original. Furthermore, judging by Love Is A Laserquest's lyrics I'm pretty positive the Monkeys are much aware of this likeness.

Jeez! What a surprise, the Arctic Monkeys found inspiration on Pink Floyd, oh my god my world is crumbling down (not). Like the time Muse got inspired for Unnatural Selection by ABBA’s Take a Chance on Me.
