Obviously an S.F. Giants postseason run wouldn't be nearly as fun without a suitably themed local rap song to go along with it. So here, fulfilling that need, is the great Bay Area rapper E-40, remaking the ubiquitous “Function” into a team anthem that shouts out pretty much every orange-wearing S.F. baseballer you love to be tortured by. Admittedly, “Giants out here tryna win somethin” isn't quite as instantly grippy as “We out here tryna function,” but hey, if it brings us a victory in NLCS Game 2 tonight (5 p.m. West Coast time!), you won't hear us complaining.
