With "Late Registration," Kanye West rules the school as his sophomore Roc-A-Fella/Def Jam album makes a chart-topping bow on The Billboard 200 this week. After a few weeks of relatively low-key activity on the album chart, West's latest leads a slew of high-profile debuts by G-Unit's Tony Yayo, Brooks & Dunn, Death Cab For Cutie, Casting Crowns, Rihanna, Eric Clapton and Bob Dylan.
