Suddenly, from the depths of your mind, up bubbles a childhood memory... a snippet of a song lyric - just a few words and a fragment of a tune. An online search, a glance at few entries to get the name of the song, a buzz over to a music repository, and a double click. Thirty-five years melt away as you listen. We live in the best of times: we still have the mysteries of the past, but now we have the means to solve them at our fingertips. Life is good.
