Ludacris has to be one of the most underrated rappers of all time. Perhaps its because of the era he came up in. Maybe its because he followed a path into Hollywood rather than focus solely on hip-hop. His double time flow is almost unparalleled, but each member of Slaughterhouse are also among the elite tier of MCs. Throw in Claret Jai on the hook for a Fast & Furious 5 soundtrack and we get our SongOfTheDay. Happy Birthday Luda!
