I made sure this one was harder. (Pause.)
Bonus points for the producer and original title of this one, Go!
[Edit]
Voting is still open, even though a couple of people guessed it already!
..Closed! The sampling song is Talib Kweli “Good To You” produced by Kanye West, original is Al Green “Simply Beautiful.” Thanks to Ivan and Mookie for the comments!

Talib Kweli – Good To You, right?
I think Kanye produced it.
0:51/0:52 gives it away 😀
Gotta love that instrumental portion that begins at 1:11, eh?
