Let's make this birthday one to remember.

44 years old (Born on August 12, 1980)

Happy Birthday, Matt Thiessen! From rocking our playlists with Relient K classics like "Be My Escape" and "Who I Am Hates Who I've Been," to your brilliant songwriting collaborations that keep us humming along—your musical genius never gets old (even if we all do!).

Here's hoping this year brings you as much joy as you've given fans through every catchy chorus and witty lyric. May the candles on your cake burn brighter than stage lights at a sold-out show—and may no one ever ask again whether Sadie Hawkins dances are still cool. Spoiler alert: they always will be thanks to you!
