Even if their music genre sucks, throw in some sexy attire, good dancing, singing in unison (something roger and pete couldn't pull off) they would have to be better than the Who.  The whole halftime music scene is so incongruous with the rest of the Superbowl, where you have the ultimate meritocracy, celebration of the greek ideal of youth and athletic prowess and then you have these semi-dead rockers...      


And, maybe yur FM radio only gets 2 stations, classic and contemporary, but seeing that you missed it, there's a whole other world of great rock music recorded since 1974.  In fact, I would go out on a limb and say in consideration of the punk, indie and grunch rock movements, the rock between 1980's and present is consistently better than the rock that came in the 30 years prior.
