Wow.. a poltergeist!

[GEN3RIC]

So recently something strange started happening. Every few minutes while I was stumbling around the net using "Stumble Upon" in Firefox, I would hear this dumb song come about while I was doing something else. I checked my processes and didnt find anything abnormal and the page I was viewing at th etime it happened was videos.google.com (while a video played) and also some guy's photography site.

The same song!

So I though this was weird but let it be. So then I click Stumble! and the next clip is this.

That's the song! Did Stumble Upon decide to scare me or something?!
