Let's make this birthday one to remember.

38 years old (Born on March 13, 1987)

Happy Birthday, Allen Stone! To our favorite "hippie with soul," may your day be filled with groovy vibes, funky rhythms, and enough cake to fuel another decade of soulful serenades. From the heartfelt melodies of "Last to Speak" in 2010 to the smooth grooves that made us sway through your self-titled album in 2011, you've consistently reminded us how good music can touch hearts—and hips!

Here's hoping this year brings you even more success (and perhaps fewer hairbrushes—your iconic curls are already perfect!). Keep spreading those positive vibrations; after all, you're proof that peace signs never go out of style.
