PORTLAND, OR—Exhausted and beyond the point of caring what music she listens to while working, 22-year-old Espresso Royale Cafe employee Jennifer Bergstrom let Paul Simon's Graceland repeat in the coffee shop's CD player for a fifth time Monday. "I've already heard 'The Boy In The Bubble' four times today," Bergstrom said. "Would hearing Paul Simon sing, 'These are the days of miracle and wonder, this is a long-distance call,' one more damn time honestly make any difference at this point?" During her 10-hour shift, Bergstrom also listened to Natalie Merchant's Tigerlily three times and a Putumayo world-music compilation twice.
