A Song That Reminds You Of Someone
The first few answers that come to mind are too personal to post in public. There's another answer that would lead me to write screens and screens of acidic horribleness that might be entertaining to read, but could lead to a lawsuit for slander. (Then again, it might be worth it, hmmm...)
When I worked as a camp counselor, the counselors had a song we listened to only when the kids (and the people in charge) could not hear it. It is the single most filthy song I've ever heard, and just thinking about it brings me back to the utter insanity and the sheer fun of that job, and being with that group of people. I refuse to post a link, but if you google "Eat, Bite" you'll probably find it.
One summer in my youth, my best friend and I, both quite broke, spent a lot of time doing whatever we could to get out of the house that might also be cheap. Loosely translated, this meant a lot of movies at the dollar theater and nursing cups of coffee for as long as possible. "Hands to Heaven" by Breathe
seemed to be constantly on the radio, and we went mad trying to figure out the words to the chorus. It took us far longer that we'd care to admit, but I will never forget being in the Burger King parking lot when he yelled, "tonight you calm my restlessness!"
I miss those days, and wish we now lived less than several thousand miles apart.
