Dan + Shay dropped a new song “10,000 Hours”, featuring their friend and pop superstar Justin Bieber. The country stars attended Bieber’s wedding last week, an appropriate segue to the release of this romantic ballad. Dan Smyers says the song is about “spending a lifetime, learning and loving your significant other,” adding, “this song is extra special to Shay and I, because we wrote it about our beautiful wives, Abby and Hannah.” Shay Mooney was excited about working with his friend. “It was cool to be able to collaborate with our friend Justin Bieber because he’s in that same boat. He just recently got married to his wife Hailey” he told Radio.com. “This song means a lot to all of us, and we hope that this song resonates as much to our fans as it does to us.” Dan + Shay co-wrote the track with Bieber, Jessie Jo Dillon, Jordan Reynolds and Jason “Poo Bear” Boyd, with Smyers producing. Dan + Shay will embark on a 37-date U.S. arena tour in 2020.
