Great song from a great album.
I wholeheartedly agree! I decided to listen to the album (for the first time) while watching the Wizard of Oz simply because of the stories I've heard of the correlation between the two (

In addition to "Time", I really like "Money", "Brain Damage", and "The Great Gig in the Sky". Hell, I like all of 'em!

It sounds like Erykah Badu borrowed a bit from "The Great Gig in the Sky"...
Thanks for the share!
