Carrie Underwood continues to shatter expectations for country music. The former "American Idol" broke yet another record last week.

Her new single, "So Small" debuted at No. 20 on the Billboard/R&R country airplay chart, which is the highest entry for a solo country female act.

Carrie co-wrote the track, which was also the week's most-added new single on the radio, according to Country Standard Time.

The track is from Underwood's upcoming album, due out on October 23.
