Songs in the key of (your) life

Well, fresh from the real excesses and laughter of actual flesh-and-blood-and-keyboard-and-surround-sound-swearing night class, I should be doing battle with the website project, but noooo, I'm sitting here, singing along to the Mary Tyler Moore Show theme song.

So what's your theme song? Not your ringtone (how passe) but the song seemingly tailor made for you (or so the voices tell you). 

And to get back on topic, will it appear on your glorious creation?

(Press) play nice kids.
