Rolling Stone Magazine ask 172 singers, songwriters, musicians, producers, and critics to rank in order of preference their favorite 50 songs of the rock era. Rolling Stone did a little math and produced The 500 Greatest Songs of All Times. This is a quiz about the songs and artists making up that list. Please keep in mind that the voters range from Elvis Costello to Ozzy Osbourne to Loretta Lynn to Berry Gordy, the founder of Motown Records.
