Lady Antebellum's "Need You Now" has reached No. 1 on Billboard's adult pop songs chart, which reflects mainstream Top 40 and Hot AC radio airplay. "Need You Now," which spent five weeks atop the trade publication's country songs chart is only the second No. 1 country song to cross over to the top of the adult pop songs chart, following Faith Hill's "Breathe" in April 2000. The Lady Antebellum single reached No. 1 on the adult pop songs chart in 10 weeks. It's also at No. 4 on the adult contemporary chart and No. 8 on the pop songs chart for contemporary hit radio stations. In addition, it's at No. 18 on hot dance airplay chart -- the first time a song has appeared there after first charting at country radio.
