Over many months, 'Fool's Gold' went through several different iterations. Knight had sampled the song's exotic loop from 'Evening Star,' a '70s smooth jazz track by Japanese kotoist Yutaka Yokokura, which had previously been sampled by the late, great hip-hop producer J Dilla. At one point, a keyboardist was drafted to mimic the loop, but everyone involved ultimately agreed it was worth paying more to sample the master recording than to save money replaying the part. That cuts into the percentage of songwriting royalties that go to Knight, but he's fine with that. "I'll take the hit, just for the good record, I want it to sound as good as possible."
