Maybe those old songs...

In the past few days I've heard "Dark Side of the Moon" and "Blitzkrieg Bop" at the supermarket, "John Barleycorn" at Starbucks and "Smoke on the Water" and "Who'll Stop the Rain" at an elementary-school spring concert (BTW you totally rock, Music Director Leo Zumpetta!). Could it be? Is good music actually making a comeback?
