When people talk about the most famous rap beefs, the feud between The Juice Crew and Boogie Down Productions usually comes up. As does Ice Cube versus NWA, Tupac Shakur versus The Notorious B.I.G., and when 50 Cent took on Ja Rule.

The beef between Jay-Z and Nas is certainly one for the books, with Jay dropping "Takeover" against the Queens legend and Nas coming back with "Ether."

Veteran Los Angeles rapper Ras Kass recently spoke about the beef and said he was there when Jay first heard Nas' diss track.

"I went out to the club," Ras told The Art Of Dialogue. "We went out and saw Jay and Dame at the club ... They played ‘Ether’ in the club and Jay was heated, and I remember that. I remember him saying, ‘Dame, tell that n**** to turn that sh*t off.’ "

“But the club was going up, and that’s when I knew it was over," he continued. "The DJ was like, ‘F*ck that’ and played that sh*t and the club went up. That’s when I knew Nas won. The streets had spoken. The DJ played it and Jay was in the building ... Nas beat Jay."

Did you think that Nas beat Jay when you first heard "Ether?"
