Let's make this birthday one to remember.

52 years old (Born on April 03, 1973)

Happy Birthday, Andreas Carlsson! You've single-handedly written the soundtrack to our pop-loving lives. From Britney Spears amplifying teenage dreams to Backstreet Boys providing endless karaoke fuel—we're still blaming you every time "I Want It That Way" gets stuck in our heads.

Your magical songwriting pen has given us iconic moments and timeless hits that refuse to age (even when we do!). As much as these artists owe their worldwide fame partly to your genius melodies, secretly we're pretty sure you're responsible for most of our guilty-pleasure playlists. Keep living life larger than a 90s boy band reunion—you're truly unforgettable!
