CSS's "Music is My Hot Hot Sex" -- y'know, that song from the iPhone ad -- is the most popular video ever on YouTube. Now lest you think the world is secretly being overrun by iPhone-owning Brazilian electro-hipsters and you didn't get the memo, don't fear; it's probably just one very big, highly-automated fan.

The video's come-from-nowhere success however has left many YouTube fans asking questions about the unprecedented traffic spike, with many suggesting that the books may have been cooked.

An in-depth analysis of the YouTube statistics by blogger Andy Baio also suggests inconsistencies in the traffic surge.

Biao points out that an examination of hits compared with user ratings shows that the Brazilian video has what he described as "a very unusual 21,487-to-1 ratio" of views-to-ratings.

He calculated the average ratio for every other video in the top 10 to be 590:1, which is consistent with a ratio of 545:1 for the top 500 YouTube videos.

In other words, far fewer viewers are leaving a recommendation after watching Music is My Hot Hot Sex than is the case across the board.

This may indicate the use of an automated, non-human method to inflate the clicks.

Hey, does anyone else remember that movie Stealth from a few years ago where the sentient superplane is listening to music online and Josh Whatshisface goes "What's he downloading?" and the tech guy is like "Everything" and you're supposed to go "Wow, that's a lot of music..."? Well? What do you think? Proof that superintelligent superplanes totally exist and are into Brazlilan electro? Or can you just not handle the truth?
