ain't no debate. DMX was the hottest rapper out those years. Jay had the biggest "single" with Hard Knock Life, but DMX was more popular. people were looking for the next "2Pac" and X was the closest thing.
something that sticks out to me was the 1999 Superbowl was in Miami. they had the superbowl concert down here, basically the Hard Knock Life tour PLUS Diddy, Mase, Mary J, and a whole bunch of other people. shyt was crazy
anyway, as we're waiting for the concert to start all we heard was "DMX, DMX!!" chants. then it would be "STOP, DROP, shut em down open up shop..." chants. then WE WANT X, WE WANT X. this happened before the show started, during the breaks between acts, and right before X came on stage.
