We don’t know what’s occurring on the inside but from the outside looking in, one thing is for sure and that is Def Jam Music Group must be pretty happy right about now. Last week Def Jam artist, Taio Cruz, went to #1 on the Billboard Hot 100 with the Ludacris assisted “Break Your Yeart.”

Fast forward one week and Def Jam’s reign continues on the Hot 100 and 200. Yes, after only moderate success with Rated R (compared to her GGGB era) Rihanna has acquired another #1 single with “Rude Boy.” This is Rihanna’s 5th #1 solo-lead single (6th overall) in her career of almost 5 years. You know what that means, there will defeinitely be no more “all black everything” for Rihanna’s music: color and sunshine straight through.

In other single news, B.o.B.’s “Nothin’ On You” featuring Bruno Mars jumped from #16 to #5.

Rihanna’s labelmate Ludacris debuted atop the Billboard 200 with his latest studio album, Battle of the Sexes. The album only moved 137,000 but it was enough to make it his 4th #1 album. At #2 was Gorillaz’s Plastic Beach moving 112, 000 copies and Lady Antebellum rounded out the top 3 selling another 105,000 copies. Sade holds on to the top 10 coming in at #6 moving 52,000 copies.
