Dan + Shay & Justin Bieber - "10,000 Hours"

check out the music video to the new viral smash hit from country's biggest duo and one of pop's biggest stars.

It's a song written by the duo with the pop mega star (with Jordan Reynolds, Jessie Jo Dillon and Poo Bear) and produced by Dan Smyers himself. The track is about the three newlywedded singer's relationships with their wives. It has all the earnestness of "Speechless," Dan+Shay's 2018 hit which remains their biggest to date while blending in the sweet sounds of an acoustic Ed Sheeran track. What it means is that we now have the highest-charting country streaming song of all time (as of October, 2019) and it potentially will be a #1 on Billboard's Hot 100.
