Dan + Shay’s “Speechless” is No. 1 on the Billboard Country Airplay chart for the fourth consecutive week.

Penned by Dan Smyers, Shay Mooney, Jordan Reynolds and Laura Veltz, the song was inspired by Dan’s marriage to Abby Law (May 2017) and Shay’s marriage to Hannah Billingsley (October 2017). The video for “Speechless” features footage from both Dan and Shay’s weddings.

“Thank you to country radio, our fans, our team, our co-writers, our wives and everyone who made it possible for us to celebrate our first four week No. 1,” said Dan + Shay, in part, via Instagram. “What an incredible way to end 2018 and an even better way to start 2019. Everyday we’re living out the movie that we dreamed up our whole lives, and that’s all because of you.”
