Rather than rushing out an album in the spring of 1968, when "Shoo-Be-Doo-Be-Doo-Da-Day" (Number 9 Pop, Number One R&B) hit, Motown waited, through the modest summer success of "You Met Your Match" (Number 35 Pop, Number Two R&B), until "For Once in My Life" (Number Two Pop and R&B) became Wonder's next mammoth single, to release an album. As a result, this album contained all three hits, making it one of Wonder's more consistent albums of the '60s, even with filler like "Sunny" and "God Bless the Child." The real find, however, is the driving "I Don't Know Why," which, when placed on the B-side of Wonder's next single, "My Cherie Amour," became a hit on its own, going to Number 39 (Pop) and Number 16 (R&B).
