Let's make this birthday one to remember.

77 years old (Born on April 13, 1947)

Happy Birthday, Mike Chapman—the master behind albums so catchy that radio stations couldn’t resist playing them on repeat! From your iconic productions for Blondie and The Knack to bringing fresh grooves alive with Purple Apple in 2014, you’ve continually reminded us all just how addictive pop music should be.

Here's wishing a fantastic birthday to the man whose musical instincts never age—even if hairstyles from some of those Blondie-era album covers do. May your celebrations today bring as much foot-tapping energy and memorable hooks as you've gifted our ears through decades of hits. Rock on forever—you're timeless!
