Underwood goes quad platinum

On Monday, Underwood was named the vocalist of the year. Underwood joins Gretchen Wilson as the only solo female country artist in the past decade to release a debut album achieving the 4 million mark.

Underwood said, "There are so many people that have done so much – songwriters, producers, all the people at the label. Country radio has been awesome to me, and they've played my music, and people have requested my songs and bought the albums and seen me in concert. I mean, it takes 8 million people to sell 4-million copies. It's just amazing what everybody has accomplished."

The disc was released Nov. 15, 2005. Her debut country single, "Jesus, Take the Wheel," was first heard on the 2005 CMA Awards broadcast and later spent six weeks atop the chart. Also going to the top were "Don't Forget to Remember Me" and current chart-topper for two straight weeks, "Before He Cheats."

"Some Hearts" has spent 49 of 51 weeks inside the country top 5, including 15 weeks at number 1.
