In 1987, R.E.M. released its hit single, "It's the End of the World." Remember the song? A string of seemingly nonsensical lyrics and unconnected short statements linked together with a fast, halting rhythm and amplified by a captivating chorus that concluded with the lyric, "and I feel fine." I remember spending hours rewinding the cassette tape (yeah, I know) in an attempt to understand and memorize the lyrics.
