9 Suprising Songs Kesha Has Written For Other Artists

This song off Spears's 2011 Femme Fatale album is definitely Kesha's biggest hit — apart from her own songs, of course!

Before Kesha broke onto the scene as a singer, she cowrote this track for Miley Cyrus in 2009.

While "Windows Down" samples Blur's "Song 2," Kesha cowrote this song. It was originally supposed to appear on her second album, Warrior, but she passed it to Big Time Rush.

Australian pop duo The Veronicas released this track, one of Kesha's first songs to be recorded, in 2008.

This poppy track was originally intended for Kesha's first album but was handed off to Charlee as the singer's debut single.

That's right, Kesha has even written for Alice Cooper!

Ariana Grande released this track — written by Kesha — for her fans online.

Remember this 2010 gem? It's Kesha's work as well.

Here's a weird one: South Korean girl group Girls' Generation picked up Kesha's "Run Devil Run" for Oh!, their 2010 album.
