Just like it has in past years, this year's WQHT's annual Summer Jam has also been liven up by many notable musicians, like Nas, Mobb Deep, The Game, 50 Cent, Amerie, Cam'ron, Jadakiss, and many more. One of the performers sang at the event held May 5, 2005, was rapper Jay-Z, whose special surprise appearance shocked the crowd of 50,000 inside Giants Stadium as they screaming and waving for the legend.
Along with Jay-Z there was The Game, who during the Sunday's show used the stage to air out 50 Cent, saying the press conference they had ever held as a fake. Some other musicians opened up the event among others Amerie, D-Block, and the Diplomats. Ghostface Killah and Sizzla performed during the D-Block set, while the Diplomats were joined by Houston's Paul Wall.
