Pop sweep May 19, 2012...

Here's a rundown of the songs debuting on this week's Billboard Hot 100 chart...

Rapper B.o.B. follows up two platinum singles from his sophomore CD Strange Clouds (the title track and "So Good") with a collaboration with country singer Taylor Swift on a song that comes in at #18, "Both Of Us"..

American Idol winner Carrie Underwood has her fourth straight #1 album (a record for the show), and the title track "Blown Away" debuts at #66..

And for that other singing competition show, The Voice runner-up Juliet Simms is the only contestant making the Hot 100 this week at #66 with her version of James Brown's "It's A Man's Man's Man's World"...

The cast of Glee released six songs from the "Choke" episode, but only the cover of Florence + The Machine's "Shake It Out" sells enough to get on the Hot 100 at #71 (one notch higher than the original. Grrrr.)

One Tree Hill actress and country singer Jana Kramer has her third all-genre hit with "Why Ya Wanna" at #97...

And finally, sibling act The Band Perry's fifth top-20 country hit sneaks into the pop chart at #100 with "Postcards From Paris"..

Meanwhile on the Adult top-40 chart, swag-rock duo Karmin's pop top-40 "Brokenhearted" debuts...

Happy Mother's Day to all the mothers out there!
