Well oasis are idiots, but they are musical genious's
i should point out that i'm not a hip hop fan, and am a fan of "guitar music", i have no problem with jay z headlining the fesival he is one of a very few rappers who can put on a show
that said it was a brilliant idea to come out to that song, but the crowd was singing along rather than cheering for what he was doing so maybe it didn't go that well
and also i've seen the entire gig, the crowd didn't sing along to any of his songs as well they don't know any, which is why even if you have it noel gallagher isn't completly wrong
thats just my 1pence anyway
