"NO-MOSS": Acts that had 2 or more songs on the Rolling Stone Top 500 Singles of All Time list. You WANT to identify these acts.
"MOSS": Any act with only one hit on the same list. Entering one of these acts ends the game. You DO NOT want to enter these acts.
NOTE: For this quiz, artists who are on the list as both solo acts and as a member of a group (e.g.: Clapton/Cream, Beatles/Lennon) are treated as separate acts.
