I'd like to give honorable mentions to Kerry Von Erich vs. Jerry Lawler at Superclash back in the late 1980's, and Spike Dudley vs. Bam Bam Bigelow at the second ECW PPV in 1997. During the latter, I was very worried about Spike's health, and for the former I was a mark and very scared at the amount of blood coming out of Kerry.
Is that going to be the belt or just the cover of the CD? I think it fails on both fronts. I would think a goal for Cena's CD is to get him some popularity with rap fans, not necessarily wrestling fans who also like rap.
