Other than the hit, it's all filler, but not uninteresting for that. There are several contributions from the Wonder team at Motown, covers of other Motown hits, and stabs at sounding like Ray Charles, James Brown, and Otis Redding. At 17, Wonder was becoming both a remarkable mimic, and an original talent on his own.
