Morgan Wallen's "Whiskey Glasses" was the most-played song on country radio in 2019. The rising singer's single tops Billboard's year-end Country Airplay chart this year.

Morgan's second career No. 1, "Whiskey Glasses" was originally released as a single in the summer of 2018. About one year later, it topped the charts. The song has also gone platinum.

Also among the Top 10 singles of 2019 are Lee Brice's "Rumor" (No. 10), Luke Bryan's "Knockin' Boots" (No. 6) and two tracks from Luke Combs (No. 5 and No. 2). No solo women are within the year-end chart's Top 10, a product of female artists' struggle to earn airplay.

There is one woman included in the year-end Country Airplay Top 10: Lindsay Ell, as Brantley Gilbert's duet partner on the No. 3 song "What Happens in a Small Town." The first solo woman to appear on the chart is Kelsea Ballerini, at No. 13, with her single "Miss Me More," followed by Maren Morris, with "Girl," at No. 26.
