See, a lot of the music I still listen to today (80's stuff) would be considering embarrasing by most people. But I'll still take Depeche Mode, New Order, The Cure over most of what you kids are listening to today.
Still... there is one act that I was actually NUTS over back in the day that is more than just a little embarrasing:
I had everything of these guys at one point - posters, the albums, a Twisted Sister black-satin jacket (rock on!); I even went to see them in concert once.
Having recently gone for a week without power, I have to say that my pick is the electrical grid. Electricity isn't just lights and tv, it's refrigeration, it's water pumps, it's heat (even gas and oil furnaces have electric components)
