Corporate partner/rapper B.o.B was on Leno last night, performing a song called "Champions" that they recorded for the Olympics and for a Duracell ad campaign. Just when you think that B.o.B can't go to lower depths in his cynicism for hits, there's this song, where he teams up with O.A.R., apparently the only crappy modern rock band who would bend over alongside Bobby for that corporate money. R.I.P. B.o.B's blog hype. R.I.P. shame. R.I.P. O.A.R. (hopefully).
