Another big step forward, with Stevie's first co-productions (including the tortured soul classic "Don't Know Why I Love Her" AKA "I Don't Know Why") and Stevie taking a larger role as an instrumentalist throughout (the clavinet debuts here, on "Shoo-Be-Doo-Be-Doo-Da-Day," "You Met Your Match" and more).
Catchy uptempo pop (title song), lowdown funk ("I Wanna Make Her Love Me"), sweet lively ballads ("Do I Love Her")... only a couple of covers here, and the older track "House On The Hill" is a jarring finish: stop the record before it comes on.
Motown...
Motown had finally gotten wise to the fact that the best material on a Stevie Wonder record had always been the original Stevie Wonder songs, and let him write more than half the selections here.
The first three tracks all hit the Top 40, with the title track doing particularly well. In a weird twist of fate, "I Don't Know Why" was put out as the A-side of the album's fourth single in early 1969, and it flopped, barely cracking the Top 40 for just a week - but the B-side, "My Cherie Amour," unexpectedly took off and zoomed to #4. That led to the cash-in album released a few months later.
