Early in 2007, Underwood began work on her second album, while "Wasted" became the fourth single taken from Some Hearts; she performed it on an episode of American Idol that March, and the following month, it hit number one on the Hot Country Songs Chart. She returned to American Idol in April as part of the show's "Idol Gives Back" benefit episode: Underwood visited South Africa and recorded an acoustic cover of the Pretenders' "I'll Stand by You," which was released exclusively on iTunes. Underwood won three awards at the 2007 CMT Awards: Video of the Year, Female Video of the Year, and Video Director of the Year for the video for "Before He Cheats." She also took home three 2007 ACM Awards in May, which included Album of the Year for Some Hearts and Top Female Vocalist. She made a third trip to American Idol late in the month for the sixth season finale, where she sang "I'll Stand by You" to a standing ovation. During the show, Clive Davis recognized Underwood's sextuple-platinum sales; Underwood was the first country artist to sell that many copies of a debut album since LeAnn Rimes' Blue in 1996. She also appeared on Brad Paisley's album 5th Gear, which was released in June 2006. She released her sophomore effort, Carnival Ride, in 2007. ~ Heather Phares, All Music Guide
