Stevie's Genius Backround Vocals in "Don't You Worry 'Bout A Thing"
Stevie starts the song by trying to impress a woman with his Spanish but he's really just speaking gibberish. He than says "Todo está bien chévere" which loosely translates to "Everything is cool" or "All is good." The phrase then comes back halfway throught the song in the form of backround vocals. Although the words are slightly separated and harder to make out.
Just goes to show how brilliant Stevie Wonder really is.
