American Idol winner Carrie Underwood’s first single sold 170,000 copies in its first week, making it the best-selling song so far this year, according to her publicist.

“Inside Your Heaven” debuted at No. 1 on four charts by Billboard magazine — the Billboard Hot 100, the Pop 100, singles sales and country singles sales.

The 22-year-old Carrie Underwood made Billboard history as the first country artist to debut at No. 1 on the Hot 100. It’s the first time a country song has hit No. 1 since Lonestar’s “Amazed” in 2000.

“My dreams continue to come true,” Underwood said in a statement. “Thanks to the fans for voting me as their Idol and for wanting to hear — and have — my music.”

The single won’t be released to radio stations for air play until July 5, said publicist Jessie Schmidt in Nashville, Tenn. Underwood is working on her debut album, which is due out this fall. source
