Oh Snap!: Jigga 1, Oasis 0 (Or Jay-Z "Covers" Oasis)
This just might be the greatest diss record of all time, and it's not even a record, per se. But it is most certainly a diss. Courtesy of Stereogum, the video of Jay-Z opening his controversial (only to rockists) set at the Glastonbury Festival by "covering" Oasis' biggest hit, the romantic ballad "Wonderwall". After that, Jay-Z launches into a re-tooled version of one of his greatest tracks.
Based on the clip, I'd say Hova's got 99 Problems, but sarcasm definitely ain't one.
