Sugarland is on top of the world today with the news that their CD/DVD combo 'Live on the Inside' has debuted at the top of both the country and the all-genre Billboard 200 album charts.

"Our fans are such great fans, and they have been pestering us for a long time to put out a live record," Sugarland's Kristian Bush tells The Boot. "We've been excited to put our show on tape and play the show in everybody's living room!"

The two-disc set was heavily promoted with an ABC television special, which was seen by 4 million viewers the night before the package's Aug. 4 release. Nearly 76,000 fans scooped up their own copy of 'Live On The Inside,' which is available exclusively at Wal-Mart for the fan-friendly price of $12.

Country music's other new release last week was Gloriana's self-titled CD, which debuted at No. 2 on the country album charts and No. 3 on the all-genre Top 200. 'Gloriana' sold 44,000 copies, making them the best selling new artist of 2009. The quartet's debut single, 'Wild At Heart,' is also the best selling song by a new country act in 2009, having sold more than 250,000 copies to date.

Gloriana continues to make new fans as they open Taylor Swift's Fearless tour, which includes a sold out show at Madison Square Garden later this month.
