Entering at No. 13, Billy Currington's third studio set, "Little Bit of Everything" (Mercury), sold 25,000 and earns the country singer his second best charting effort. His prior album, "Doin' Somethin' Right," peaked at No. 11 on The Billboard 200 in 2005.

Other debuts this week include indie singer/songwriter Ingrid Michaelson's "Be OK" (Original Signal) at No. 35 with 15,000 and cellist Yo-Yo Ma's "Yo-Yo Ma & Friends: Songs of Joy & Peace" (Sony Classical) at No. 41 with 12,000.
