I long since gave up complaining about who was likely on. If I don't like it, I can ignore it/ chat to friends whilst it's on. Most of the artists that have appeared don't get me terribly excited is all.
But Dre, Snoop and the rest properly do. There were a huge part of my musical upringing as was grunge, 70s/80s rock and metal.
If Pearl Jam or the Foos ever do the half time show, I may just lose my sh stuff.
