Excerpt from a All Shade Zone blog post on Beyonce

A certain flop blog thought that mentioning Rob Fusari would help them score some points. When in actuality Rob Fusari only shows that Bey does give props where props are due. Rob wanted to RE-play the infamous Stevie Nicks guitar riff sampled on “Bootylicious” so he can get credit for it. Instead, Bey and Mathew opted to use the actual sample and give credit where it was due, to the originator Stevie Nicks.
Never was there any question about her writing the lyrics it was simply Rob being mad they wouldn’t let him take credit for Stevie’s instrumental sample which meant less money for Rob [ain't that the reason that he's really mad??]
