10 Musical Superstars You Never Knew Wrote Other Artists' Hit Songs

10. Ed Sheeran

Ed Sheeran is a titan in the industry. With four albums and 17 EPs under his belt, Sheeran puts the "writer" in "songwriter." Since his first single, The A-Team, was released in 2011, the singer has released 41 singles. From rap to pop, the Brit's original indie-style sound has successfully evolved into a variety of genres.

Aside from writing his own tunes, he lends his pens to other artists. One Direction, you may have heard of them, released a hit single called Little Things off their second album, Take Me Home. The Divide-crooner penned two more songs for the boy band, including another hit off the same album, Over Again.

Sheeran's songwriting side-gig demonstrates his versatility as an artist. His writing catalog includes Major Lazer's Cold Water and even Little Mix's Women Like Me. Not only has the red-headed crooner written the lyrics to some of Justin Bieber's top singles, but you can hear him in Bieber's Love Yourself.
