Lifesong is the second studio album by American Christian rock band Casting Crowns, released on August 30, 2005 by Beach Street Records and Reunion Records. Produced by Mark A. Miller, Lifesong was the follow-up to the band's self-titled debut album. Although the unexpected success of the first album led to tremendous demand for new music from Casting Crowns, lead vocalist Mark Hall was advised by Steven Curtis Chapman (a co-producer of the debut album) and Mac Powell not to worry about commercial expectations. Lifesong, which has a pop rock and adult contemporary sound, focuses on challenging believers and indicting piousness and hypocrisy in the Christian church. Worship themes are also prominent in the album.
Lifesong was received positively by music critics. Many critics praised the album's songwriting, although others felt the album's sound was derivative. The album and its singles were nominated for many awards, with the album winning the Grammy Award for Best Pop/Contemporary Gospel Album at the 48th Grammy Awards and the Dove Award for Pop/Contemporary Album of the Year at the 37th GMA Dove Awards. It debuted and peaked at number nine on the Billboard 200 and number on the Billboard Christian Albums chart, selling 71,000 copies in its first week. The 15th best-selling Christian album of the 2000s in the United States, Lifesong has been certified Platinum by the Recording Industry Association of America (RIAA) and has sold 1.4 million copies in the United States. All of the album's singles topped the Billboard Christian Songs and Hot Christian AC charts.
