As

 This song is a classic. 

I'm sure you've heard it somewhere floating in the air...Maybe at a backyard BBQ, while shopping, dining, or even coming from your car radio. Stevie Wonder is a gem in the music world, and this song alone proves his brilliance— the man was a hit machine!

And if you haven't ever heard this one, then I am more than happy to be the one to introduce you. Don't let the slower beginning fool you, this one picks up and gets groovin'.
