Stuck In Your Head

I currently have a song very firmly stuck in my head.

I was watching a rerun of Scrubs late last night and after the episode I started humming on a song. After a while I realized that the song I was humming was from a Scrubs episode, but not the one that I'd just watched. It turned out to be the following song:

I've seen this Scrubs episode quite a number of time and I really like it, especially this sequence with Colin Hay singing "Overkill". It's just such a catchy song. I consider this episode a real classic among Scrubs episodes. It's not just that's good, it contains so much that is the essence of Scrubs, with all the relational conflicts and stuff.

Anyway, so how does songs get stuck in your head. It seems research find it mysterious too but this article explain it as some kind of brain-itch. And the cure seems to be to scratch it. The thing is, I seem to be extremely susceptible to getting songs stuck on my head. Once I had "Norwegian Wood" by Beatles in my head for several months. But it should be said that I didn't listen to the song even once during that period and when I finally listened to it a couple of times it went away. So I'll be listening to "Overkill" quite a lot for a few days now, so as to "scratch the itch". But not that I mind, it's a good song.
