Meanwhile, Jana Kramer scores a top five hit and Carrie Underwood returns to No. 1 on Country Albums.

Little Big Town's "Pontoon" tops a second Billboard songs list -- this time Country Songs -- eight weeks after it became the group's first chart-topping song on Country Digital Songs (July 21). The quartet's previous best rank on Country Songs was noted when "Bring It on Home" stopped at No. 4 six years ago.

On the digital tally, "Pontoon" has amassed four weeks at the summit and ranks at No. 2 (78,000 sold). Nielsen SoundScan reports 1.1 million downloads sold since its release in May.

Meanwhile, Darius Rucker is the most recent benefactor of coordinated hourly play at Clear Channel-owned country stations, an August 27 surge that lifts the South Carolina native to a career-high No. 26 debut on Country Songs with "True Believers." The handsome start surpasses Rucker's previous high debut, a No. 44 arrival with "Come Back Song" on the July 10, 2010 chart. The track introduces the artist's next album, which hasn't been titled or scheduled, but is expected sometime in early 2013.

Easton Corbin and Carrie Underwood freshen up the top 10 on Country Songs, as Corbin's "Lovin' You Is Fun" becomes his third top 10 (14-9) and "Blown Away" brings Underwood's top 10 tally to 16 (12-10). Corbin's first two singles both reached No. 1, and Underwood has an even dozen leaders on the audience chart.

Billboard's Chart Beat columnist Gary Trust notes that Underwood maintains her perfect record of reaching the chart's top 10, as all 16 of her promoted (non-holiday) radio singles have reached the top tier, a record among women in the tally's 68-year history -- she passes Taylor Swift, who has sent her first 15 such releases to the top 10.

Also noteworthy on Country Songs, singer/actress Jana Kramer's "Why Ya Wanna" logs the best rank for a woman's first promoted single since Underwood's chart topping "Jesus, Take the Wheel" in 2006. With 37 chart weeks, Kramer's track is the slowest top five climb for such a song since Jamie O'Neal's 2001 leader, "There Is No Arizona" (25 weeks).
