Stevie Wonder was beginning to rebel against the Motown hit factory mentality in the early '70s. While he certainly hadn't lost his commercial touch,
Wonder was anxious to address social concerns, experiment with electronics, and not be restricted by radio and marketplace considerations. Still, he gave the label another definitive smash with the title track, while sneaking in a cover of
the Beatles' "We Can Work It Out" and penning more intriguing tunes like "I Can't Let My Heaven Walk Away" and "Never Had a Dream Come True." ~ Ron Wynn
