After Underwood won Idol, she released her debut single, "Inside Your Heaven," which shot to No. 1 on the US chart, which was incredibly unusual for a country single. It led into her debut album Some Hearts, which hit No. 1 on the Billboard chart and cemented Underwood as a bona fide pop country star. She's released five other studio albums, gone on nine tours with another coming in 2019, and won seven Grammy Awards.
