Query: This CD set defines the Wonder of Stevie Wonder

I think that this CD best compiles the most popular songs of Stevie Wonder. I never knew how many people have redone his songs until I heard these CDs. Stevie Wonder's ballads are the greatest. There won't ever be another artist like Stevie Wonder-so deep and sincere in emotion. None of that superficial stuff that you hear today. His music is pure soul.
