I never cease to be amazed at how quickly a song can take you back. I loaded the changer this morning with a mix of new CDs and ones that had been in storage for two years. The first song to come up? REM’s “World Leader Pretend” from 1989’s Green. Instantly it’s fall in Newport News, September 1989. I’m a senior in high school, newly confident about my place in the world and arguing about REM with my friends Rob and Matt at Patrick Henry Mall.
