Quick quiz: Who won this past year's "American Idol"? If you answered, "I dunno," "Who cares?" or "Crystal Bowersox," you were wrong (and probably in the majority — sorry, Lee DeWyze). "Idol's" relevance in 2011 remains to be seen, but if 2010's lackluster season is any indication, J. Lo and that Aerosmith dude have a lot of work to do.
