Major Hit: "Rapper's Delight" (1979)

Other Hit: "8th Wonder" (1980)

Hip-Hop's first big hit record was almost its first one-hit wonder. With its beat-jack of the bass line from Chic's "Good Times," The Sugarhill Gang showed right from the start that the formula for rap success was the perfect combination of a catchy beat and simple rhymes. Nothing too complex. And Grandmaster Caz wrote Big Bank Hank's verse, too. (Apparently credibility wasn't that big of a deal back then either.) One year later, the Gang worked the same formula to perfection and dropped another, less well-known hit, "8th Wonder," which they followed with another chart hit, "Apache." The Sugarhill Gang might not have had eight hits, but they're definitely not one-hit wonders.
