In January, Dan Smyers and Shay Mooney of Dan + Shay scored their seventh No. 1 single as “10,000 Hours,” which features Justin Bieber, ascended to the top spot on both the Billboard Country Airplay chart and Mediabase chart. The tune has also spend 20 weeks at No. 1 on the Billboard Hot Country Songs chart.

Co-penned by Dan, Shay, Justin, Jessie Jo Dillon, Jordan Reynolds and Jason Boyd, “10,000 Hours” features Shay and Justin trading vocals alongside Dan’s production. The tune is the first new music from Dan + Shay since the release of their 2018 self-titled album, which spawned three No. 1 singles: “All to Myself,” “Tequila” and “Speechless.”

As Dan told Kix Brooks of American Country Countdown, their collaboration with pop star Justin Bieber has helped the duo’s music reach new places they “never dreamed of.”

“This has been really cool,” says Dan. “I mean, obviously, ‘Tequila’ and ‘Speechless’ changed our world in such a big way, but this song has reached new places that we had never dreamed of having music out [in], so to have people listening to country music all around the world is unbelievable. And, Justin, I know, is excited to be a part of it. He loves country music [and] has always been a fan, so having him on our song is pretty surreal. I have to pinch myself. I’m like, ‘We’ve got like the biggest superstar in the world on our song!’ It’s insane.”
