Kanye West's braggadocio has nothing on Lil Wayne's boasting: The New Orleans rapper's latest victory lap around the country is dubbed the "I Am Music" tour. Then again, Weezy's 2008 was rather spectacular, between Tha Carter III selling more than a million copies during its first week of sales and the ubiquity of "Lollipop" and "A Milli." Openers for the main event include Timbaland protégé Keri Hilson, a pop songwriter whose debut artist album is due next year; vocoder tastemaker T-Pain; R&B queen Keyshia Cole; and Gym Class Heroes, the hip-pop friends of Fall Out Boy.
