Music genres sometimes blur, and here’s a doozy:  Justin Bieber, one of the world’s top Pop stars, and Country duo Dan & Shay, have a hit:  “10,000 Hours” is romantic, so-sweet, upbeat, charming, clever and just a little bit Country, with a cutesy-catchy hook.

I’d spend ten thousand hours and ten thousand more
Oh, if that’s what it takes to learn that sweet heart of yours
And I might never get there, but I’m gonna try
If it’s ten thousand hours or the rest of my life

Dan & Shay are Country music staples but this is “The Biebs” first foray into the format, however, he’s friends with singer/songwriters Dan Smyers and Shay Mooney; they attended his recent wedding, and he’s guesting on their next album.

“10,000 Hours” is charting #17 on Adult Top 40, #20 on Top 40 and #21 on Country.

Forty years ago, The Doobie Brothers were also counting the time—albeit minutes not hours, and with a whole other point of view.  The 70s.
