Trying to reinvent her image, Clarkson decided to part ways with American Idol management and developed a more pop rock sound for her second album, Breakaway (2004).It sold over 12 million copies worldwide and earned Clarkson two Grammy Awards.
Clarkson's debut single, "Before Your Love/A Moment Like This", topped the US Billboard Hot 100 chart and became the best-selling single of 2002 in the nation.
It was followed by the release of her debut studio album, Thankful (2003), which debuted at number one on the Billboard 200 chart.
After debuting at number 60 on the Billboard Hot 100 chart, the single climbed to number 52 the following week, and subsequently ascended to number one.
It broke a 38-year-old record set by the British band The Beatles for the biggest leap to number one.
Her seventh and final album under RCA, Piece by Piece (2015), was her third album to debut at number one on the Billboard 200.
Its title track became her eleventh top-ten single on the Hot 100.
She appeared as an extra in a few television series such as Sabrina, the Teenage Witch and Dharma & Greg and briefly worked with musician Gerry Goffin to record five demo tracks in trying to secure a record deal.
Lack of other career opportunities and a fire incident in her apartment forced Clarkson to return to Burleson, where she worked at a movie theater, promoted Red Bull energy drinks, and worked as a telemarketer and as a cocktail waitress in a comedy club.
She sang at her high school talent show, after which an audience member shared some inspiring words with her: "God has given you this gift. You're destined to sing." Clarkson continued singing and soon started classical training, hoping that music would be her ticket to a college scholarship.
