"I Don't Know Why" (sometimes listed as "Don't Know Why I Love You") is a song by American singer-songwriter Stevie Wonder, from the 1968 album For Once in My Life . It was released as a single on January 28, 1969, with "My Cherie Amour" on the B-side. A few months later, the single was re-issued with sides reversed because of the growing popularity of "My Cherie Amour", which became a Top Ten hit. [1]
Cash Box stated that "Wonder is softened just a trifle on this slower and more dramatically developing ballad." [2]
The single peaked at No. 39 on the US Billboard Hot 100. The song was recorded when Wonder was 18 years old, and became a moderate hit single, together with "You Met Your Match", another song from the album. It also showcases Wonder's talents on the clavinet.
