Ice Cube says his song "No Vaseline" is the best diss track of all time. These are some strong words being that there are some preeeetty heavy diss tracks in Hip-Hop.
"No Vaseline" was a diss to Eazy-E and the entire N.W.A including Jerry Heller. It was a tough diss track and had some strong words. When it first dropped, N.W.A thought they were done for according to the infamous movie, "Straight Outta Compton."
This specific diss was most definitely fire and easily top 10 of all time but #1 may be a stretch in my opinion. #1 is tied between TuPac's "Hit 'Em Up" and Nas' "Ether."
You be the judge. This is Hip-Hop!
