I think my brain nearly exploded!

Just a min ago I was working away while listening to the radio. Sarah McLachlin's "Building a Mystery" the acoustic version was on... All of a sudden I got a headache in the back of my head and I realized it was the song! She is continually singing the same irritating, headache inducing note! I had to shut the radio off before I went crazy! I used to really enjoy that song but I don't think I will ever be able to listen to it again.
