Shania Twain’s New Album Debuts at No. 1
It didn’t take long for Shania Twain to climb up the album chart รณ her new disc, “Up!” debuted at No. 1.
The country star’s first release in five years sold a whopping 874,000 copies in its first week in stores, according to industry figures released Wednesday.
That nearly doubles the first-week sales of another country star who’s enjoyed major crossover success, Faith Hill, whose “Cry” debuted at No. 1 a month ago with about 472,000 copies sold.
“Up!” is composed of two discs, with the same songs in the same order on both; the “red” disc contains the pop-rock versions, while the “green” disc holds the country-tinged versions.
Debuting at No. 2 was the 11th volume of the US version of the “Now That’s What I Call Music!” series. The latest compilation, which includes Nelly’s ubiquitous “Hot in Herre” and songs from Coldplay, Norah Jones, Eve and Creed, sold about 316,000 copies.
And Audioslave’s self-titled debut entered the chart at No. 7, selling 162,000 copies. The band features members of Rage Against the Machine and former Soundgarden lead singer Chris Cornell, who stepped in when Rage frontman Zack de la Rocha left the band two years ago.
