Back in college I bought the new CD “Undertow” by the band Tool and got into bed to listen to it through my big fancy headphones. As the album ended, the sun set and I fell asleep. Well the album didn’t actually end after the last song. While I slept, the CD player kept playing, going through a bunch of silent tracks. Then suddenly, the “secret” track came on. It blasted through my headphones and I awoke to a completely dark room, confused and frightened. It took me a moment to remember where I was and to figure out that I was wearing headphones. That CD has scared me ever since.
