Wait, Who Wrote That? 15 Shocking Songwriters Behind Pop Hits

So, we were sitting around the VH1.com offices, discussing the various merits of Britney’s bad-good hit “Till the World Ends,” when we remembered that pop tart Ke$ha actually wrote the song (yep, the gin-soaked starlet is a total wordsmith)! Which begged the question — how many other pop stars in their own right had penned huge smashes for other artists?

  • Beyonce_NeYo

  • Kesha_Britney

  • Missy_Ciara

  • Usher_WillIam

  • avirllavigneKellyC

  • bruce-patti

  • bruno-ceelo

  • jessie-miley

  • keri-hilson-pussycat

  • id_mad_2.jpg

  • paula-kylie

  • pink-lambert

  • the-dream-milian-bieber

  • prince-stevie

  • prince-bangles

The answer? More than you’d think. For many up-and-coming artists, songwriting is a clever way to break into the industry (while also racking up ultra-lucrative writing credits). And for established artists, crafting tracks for other singers is a way to explore sounds or subject matter that might not jibe with their own persona. Hence, Bruce Springsteen penning¬†The Pointer Sisters’¬†steamy ’70s soul ballad, “Fire.” So deliciously random!

From Keri Hilson to Pink, here are our favorite fifteen artists secretly behind some of the top smashes of our time.
