Wow... just wow! It's currently #29 on billboard and has only been played 50 times on US radio. Number of views has doubled since your post and it's blowing up faster than Gangnam Style did initially!
What the fuck is it with songs like this? Is there something subliminal? Illuminati-ish? Reading some of the comments, it's clear everyone else is wondering the same thing... "Why can't I stop watching this?" "I don't even know what I just watched or why or how this video even got loaded in my browser!"
It's kinda along the lines of those unexplainable mega-hit songs that had none of the traditional things you find in successful hit songs. A few examples that readily come to mind:
Cars - Gary Neuman
Whip It - Devo
Walk Like an Egyptian - Bananarama
Money (That's What I Want) - The Flying Lizards
Pretty much anything by Sinead O'Connor
Spirit in the Sky - Norman Greenbaum
