People of the Sun by Rage Against the Machine---I think it's one of their most innovative songs...Tom Morello plays the whole thing with an Allen Wrench instead of a pick. Who would think to do that? Also, Revolver by Rage is a great song because it has kind of a toned-down verse part, and then it builds up into an awesomely intense chorus. And then, there's Since I've Been Loving You, Babe I'm Gonna Leave You, and Immigrant Song by Led Zeppelin. Since I've Been Loving You has this awesome blues-y vibe in it, Babe I'm Gonna Leave You has a sweet kind of Spanish sounding theme to it, and Immigrant Song is just plain awesome. Oh, and I can't forget the stirring and unforgettable Halo theme. It still sends chills up my spine every time I listen to it. In Summary: I have too many best songs of all time.
