With her exposure from "American Idol," Underwood's debut single, "Inside Your Heaven", became the first song by a prominently country artist to ever debut at number one on the "Billboard" Hot 100. Underwood continued to have crossover success in 2006 and 2007, with her hit single "Before He Cheats", which was notable for becoming a success on mainstream pop radio "without" a more "pop-friendly" remix. Underwood has had additional, but more spotty, success on pop radio since. Nonetheless, she disproved the notion that country artists, especially country female artists, were limited to success only within one genre. Further supplying that evidence was the success of Taylor Swift, who released her debut album in 2006.
