"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.
Cash Box stated that "Wonder is softened just a trifle on this slower and more dramatically developing ballad."

Rolling Stones version
A rendition of "I Don't Know Why" by the Rolling Stones is included on their 1975 rarities compilation Metamorphosis. It was recorded on July 3, 1969, during the sessions for Let It Bleed. It was also the night that news broke of former guitarist Brian Jones' death, less than a month after he had been fired from the band.
The song was also used as the B-side for their 1975 single "Try A Little Harder", and peaked at No. 42 on the US Billboard Hot 100.
