Let's make this birthday one to remember.

51 years old (Born on October 12, 1974)

Happy Birthday, Shane! Are your eyes still blue? Because after all these years of hits and Grammy wins, we're pretty sure they're sparkling gold by now. From serenading us back in '99 to producing chart-toppers for Kacey Musgraves—your talent ages better than fine whiskey.

Here's hoping this birthday is as timelessly cool as the songs you've crafted (and maybe even catchier). May you celebrate surrounded by friends who appreciate good music—and cake—as much as we appreciate your incredible contributions to country tunes. Keep making magic happen; Nashville wouldn't sound nearly so sweet without you!
