The label picked up its first hit that year with a creation of Philadelphia International's other great production/songwriting team, Gene McFadden and John Whitehead: The O'Jays breakthrough hit, "Back Stabbers." But the next single by the group, "Love Train," bore the Gamble and Huff stamp and defined the new genre perfectly. Thom Bell, another producer at the label, helped create the ballad sound of Philly Soul with the Delfonics' late-Sixties hits, and would later move to other labels and oversee big hits in the style with the Stylistics and the Spinners.
The rest of the decade's R&B was ruled in part by Philly Soul, as even artists not associated with the genre capitalized on the sound's popularity with smashes like Hall and Oates' "Sara Smile," Lou Rawls' "You'll Never Find Another Love Like Mine," and Elton John's ode to the sound, "Philadelphia Freedom." Ironically, Philly Soul's lush romanticism and simple funk gave birth to the rise of disco later in the decade, a genre which would eventually supplant it, though the genre's stars merely adapted slightly to stay popular.
