Don't You Just Love Finding the Song Sampled in One of Your Favorite Songs?

I was always really into this song...I mean like real into it. It's catchy, has a great meaning, and  the lyrics are not only clever, but easy to understand. Like anyone can sing this if they wanted. Anyway I was listening through the ole I-tunes library the other day and came across the Bob Dylan song Lay Lady Lay. I think if you all listen for one second you'll see how it relates to the Cudi song.
