Fergie on Top of the Charts

Fergie, the singer from Black Eyed Peas, just got her second number one single:

Black Eyed Peas singer Fergie earned her second No. 1 on the Billboard Hot 100 singles chart Thursday with "Glamorous," a tune featuring rapper Ludacris.

Thanks to 166,000 digital downloads, the track jumped seven places to end the two-week reign of New York rapper Mims' "This Is Why I'm Hot," which slipped to No. 2.

In its nine week history on the Hot 100, "Glamorous" has fallen in and out of the top-10 due to its availability online. Fergie's first single, last year's "London Bridge," was her first No. 1 on the chart.

Akon's "Don't Matter" slipped one to No. 3; the R&B singer is also the featured artist on Gwen Stefani's "The Sweet Escape," as it similarly fell one to No. 4.

Patrick Stump can be heard on the No. 5 and 6 tracks, as the featured artist on Gym Class Heroes' "Cupid's Chokehold" (up two to No. 5) and in his own band Fall Out Boy, whose "This Ain't a Scene, It's an Arms Race" held at No. 6 for a second week. Rock band Daughtry's "It's Not Over" re-entered the top-10, rising four to No. 7.

As for the others, who are they? Or is that a sign that I'm getting old?
