It's impossible to come up with the best rap song ever, but lol at it being Hit em up. Pac stans are hillarious (basically like weezy stans today*). But as for some dope songs that are up there as my favorites-
"Mo money mo murder" by AZ ft. Nas
the original version of "renegade" by Royce da 5'9 ft Eminem
"u don't know" by Jay-Z
"D'evils" by Jay-Z
"The ruler's back" by Slick Rick
"Rather Unique" by AZ
"C.R.E.A.M." by Wu-Tang
"Life's a bitch" by Nas ft. AZ
And for some more recent songs that I don't really think are best but I love...
"Int'l players anthem" by UGK ft. Outkast
"The Champ" by Ghostface
"The cool" by Lupe Fiasco (the song not the upcoming album)
"kick, push" by Lupe Fiasco
"Desire" Pharoh Monch
"The Game" by Common
