Soundtrack

Early on I realized that the things going on in my head weren't quite like everybody else's. At least, not in the heads of the people closest to me. I never believed I was so unique that no one else's was the same, and I certainly never believed that it made me special (maybe the opposite even), but I knew I was definitely alone in my local control group. One of the differences I picked up on was the soundtrack of music that's always playing between my ears. Even when I'm not actually listening to music, it's there, a constant presence, a piece of me that's been around for as long as I can remember. I can't always identify the song/tune/beat, and I can almost never tell you the title or the artist (as some of my more musical or trivia-minded friends will tell you with frustration), and it's certainly never helped me keep a tune or play an instrument, but it's there. Sometimes louder, sometimes quieter, sometimes appropriate, sometimes incongruous, sometimes angry and sometimes completely unnoteworthy, it's there. And it has always meant that music plays an important and variable role in my life.
Lately, it's become more prominent than it has been in the recent past (I have no idea why), and it's made me think about how I would/could/should describe the soundtrack of my life. What songs are on it? Why? What does it sound like? Does it come from an internal, intrinsic piece of me, or is driven by my surroundings and reactions to them? Is there some way I can ask my kids if they've inherited this trait without scaring the shit out of them and finally convincing them that I'm bat-shit crazy? Which song/tune/beat plays most often and why? Etc., etc., etc. You get the picture.
