The power of Madonna wasn’t enough to sustain the Glee cast’s #1 standing on Billboard’s Top 200 Albums chart. In fact, Atlanta singer/rapper/multi-instrumentalist B.o.B sees his debut LP The Adventures Of Bobby Ray arrive on top this week (though he only moved a ho-hum 84,000 copies), which bumps Glee all the way down to #10. Ouch! Meanwhile, over on the Hot 100, Usher’s “OMG” inches up to #1. Check out Usher’s track record at the top of the chart below.

Billboard notes that Usher’s rise with “OMG,” now his ninth #1 single on the Hot 100, is due to both increases in radio impressions and digital download sales. Also, since his string of chart-toppers began in 1998, no one has amassed as many #1 hits in that time.

Here is the full list of Ush’s top singles:

1. “Nice And Slow” (1998)
2. “U Remind Me” (2001)
3. “U Got It Bad” (2001)
4. “Yeah!” (2004)
5. “Burn” (2004)
6. “Confessions Part II” (2004)
7. “My Boo” (2004)
8. “Love In This Club, Part II” (2008)
9. “OMG” (2010)

Ah, “U Remind Me”—total jam!

Expect the inevitable #1s compilation shortly. Back on the Top 200 Albums, Usher’s Raymond v. Raymond falls one position to #6 this week.

And following the #1 debut of B.o.B’s album, Bullet For My Valentine’s Fever goes in at #3 while Melissa Etheridge’s tenth studio LP Fearless Love debuts at #7.

Rounding out the week’s new entries in the Top 10 is Nickelodeon teen queen Miranda Cosgrove’s first album Sparks Fly, which goes in at #8. We’ll chalk it up to the track “Hey You” being co-written by Kip Winger.
