What music is in your head?

Let's face it, every person walks around with a sound track playing in their heads. Most of the time the music in their mind is a direct connection to how they feel at that moment. I, for instance, can be in a good mood and I will have a song like Chemical Bomb, by the AquaBats, or maybe some good old Dean Martin playing over and over in the background of my brain. If I am angry, my music gets a bit more sinister, anything from Ministry's Psalm:69 album, or perhaps The music from Conan the Barbarian, any thing other than 'In the hall of the mountain king', which is a song that I sometimes hear in my head when I am feeling evil and silly, kinda like Loki before the whole eyes ripped out, serpent dripping venom for an eternity thing. Of course if I am about to fight, I have no real soundtrack going on in my head and I just sit hoping that two or three people with bagpipes will just randomly start playing from local rooftops, nothing makes a fight more fun and vicious than the bagpipes.
This line of reasoning got me thinking about the music in other peoples heads. I wonder what is going through the heads of those guys in blue Van Heusen shirts when they walk down the street, looking so cocky after a hard days work banking from a soft chair. Is it one of the "jock rock" songs like Who let the dogs out? Or is it something even more pathetic, like Creed? With so many people on the planet, someone must be walking around with Hootie and the Blowfish or Blues traveler as their "gettin' mean, let's go find some bitches" music. How about the fat guy in the leather three quarter length jacket, a Diecide shirt and Black Number One in the hair, what music is in his head? Sadly, if it is a Metallica song, it is probably off of the black album or ...And justice for all. And definitely not off of one of their actual good albums, Kill 'em all, being my favorite, you could still hear the Mustane in that one. If he has anything heavier of more evil than the golden ticket song from Willy Wonka, I would be shocked. What about the Debby on the street? I would say the sound of florescent lights humming before they burn out is about the limit their minds could handle. That is why I like to sit with a couple people outside of a bar, drink some rye and play the "what music is in their heads?"game. It is a load of fun. Easy to play as well, one person has to guess the song in the persons head as they walk by and someone else says what should be in their heads. Try it, it's great.
