"Some Hearts" is a song written by Diane Warren. The track was originally written for Belinda Carlisle, who recorded it as a demo for her 1987 Heaven on Earth album, but it was not included on the album. It was released as a single by Marshall Crenshaw from his 1989 album, Good Evening, but it failed to chart. Singers that have covered the song include Kelly Levesque, featured in the 2001 film America's Sweethearts, Maria Arredondo for her 2004 album Not Going Under, and Carrie Underwood for her debut album of the same name.

In 2005, it was recorded by Carrie Underwood as the title track of her debut album, Some Hearts, and was the album's third single. It was only released to pop and adult contemporary radio in the United States in November 2005, around the same time that "Jesus, Take the Wheel" was released to country radio. "Some Hearts" peaked at number 12 on the Billboard Adult Contemporary chart and reached number 22 on the Adult Top 40 chart. The song had no accompanying music video and was not released to country radio. It has sold over 207,000 copies in US as of February 2010.

Underwood performed the song at the 2005 Billboard Music Awards, the half-time of the 2006 NBA All-Star Game in Houston, on an episode of The Ellen DeGeneres Show and during her promotional tour for the album's release. The song was used in early commercials for American Idol's website during the sixth season of the show, until Daughtry's "Home" was used after Hollywood week.
