No. 20, "So Small," Carrie Underwood (2007)

No. 26, "Cowboy Casanova," Carrie Underwood (2009)

Just two other songs by women have arrived in the top 30 during the Nielsen BDS era. Notably, the top six have done so this decade. Faith Hill's "Mississippi Girl" launched at No. 27 in 2005. The only top 30 debut of the '90s by a female artist? Twain's "Love Gets Me Every Time," which opened at No. 29 in 1997.

Just as "So Small" resoundingly heralded the release of Underwood's sophomore album, "Carnival Ride," two years ago, "Cowboy Casanova" introduces "Play On," due Nov. 3.
