If you keep up with pop culture, you’ve definitely heard Sia (and seen her, usually with her face covered a blunt-cut wig.) What you might not know, however, is that the Australian singer—whose full name is Sia Furler— is also a top-notch songwriter, having churned out hits for a staggering array of musicians including Rihanna, Beyoncé, Ne-Yo, Oh Land, and Celine Dion.
Sia’s songs share a sweeping, anthemic quality—all of which could easily be sung by the 38-year-old herself (and some have been, though not in an official capacity.) Below, we’ve rounded up 20 songs you never knew were written or co-written by Sia.
1. “Diamonds” by Rihanna
Sia told the New York Times that she wrote the dramatic “Diamonds” in 14 minutes, and was shocked that Rihanna chose to stick to her exact inflections when recording the hit. Listen to Sia sing it herself here.
2. “Pretty Hurts” by Beyoncé
The story behind this positive anthem is almost as enticing than the sweeping song itself. According to the New York Times, Sia emailed the song to her friend Katy Perry, but Perry didn’t see the email. So Furler passed it to Rihanna’s camp, who ultimately never paid the fee to secure the track. “When Beyoncé heard it, she slid into home base and just closed the deal,” Furler told the Times.
The story gets better: Last summer, Dr. Luke, one of Perry’s superstar producers, got a copy Beyoncé‘s version before it came out and played it for Perry, who loved it. She texted Furler: “I’m pretty hurt you never sent me this song.” Furler responded: “Check your email.”
3. “You Lost Me” by Christina Aguilera
This track—sung brilliantly by Christina—was part of the star’s 2010 album “Bionic,” which ultimately flopped despite some standout songs like “You Lost Me.”
4. “Breathe” by Jessie J
Thanks to their insanely powerful pop voices and penchant for big songs, Jessie J and Sia are a perfect hit. “Breathe” was part of the British singer’s second studio album, “Alive.”
5. “Perfume” by Britney Spears
This song was part of Brit’s eighth studio album, “Britney Jean.”
6. “Double Rainbow” by Katy Perry
“Double Rainbow“ was recorded by Perry for her fourth studio album, Prism. Having come up with its title during a yoga class, Perry wrote the song with Sia.
7. “Radioactive” by Rita Ora
This song ended up becoming the fourth single from her Ora’s debut album.
8. “Acid Rain” by Alexis Jordan
A bit of a departure for Sia, this track written for Jordan—who rose to fame after appearing on “America’s Got Talent”—has more of a dance/club vibe than a sweeping pop anthem.
9. “Let Me Love You (Until You Learn to Love Yourself)” by Ne-Yo
Co-written by Sia, this dance-meets-R&B track became a huge hit, commercially and critically.
10. “Loved Me Back to Life” by Celine Dion
If there ever was a match made in vocal heaven, it’s Sia and Celine. Despite that fact that Dion gets a bad rap for melodramatic adult contemporary pop, her powerhouse voice is incomparable, and Sia managed to co-write her a stunning “comeback”song that proves it in a new and modern way.
11. “Strange Birds” by Birdy
Sia co-wrote the soaring”Strange Birds” for Birdy, which has been called one of the British singer-songwriter’s career highlights.
12. “Cannonball” by Leah Michele
The “Glee” star has credited this anthemic pop song with helping her deal with her grief following boyfriend Cory Monteith’s death. “[Sia] said to me ‘How do you feel in this moment?’ And I said ‘I just feel like grief is the hardest thing in the whole world. And you have the opportunity, at a certain point, to either let it kind of take you down or try your best to rise,” Michele told MTV. “And I said ‘I need to get out and I need to move forward in his memory and do everything I can for him.’ ”
13. “Standing on the Sun” by Beyoncé
This summery jam was co-written by Sia, and appeared in Bey’s H&M campaign last summer before officially landing on the Internet in April.
14. “Green Card” by Oh Land
Sia co-wrote this track for the Danish electro-pop star’s second album “Wishbone,” has it’s been called the record’s standout track. “[Sia’s] crazy in the best possible way,” Oh Land told Gigwise. “Sia is one of the funniest people I’ve met, she’s very sweet, a very loving person. She’s blowing up all over the place.”
15. “Sexercise” by Kylie Minogue
Sia also co-wrote this slinky, sex-tinged track that appeared on Minogue’s twelfth studio album Kiss Me Once.
16. “Godzillionaire” by Brooke Candy
Sia co-wrote this banger by rapper Brooke Candy with Diplo in 214.
17. “Break the Walls” by Fitz and the Tantrums
In true Sia style, this soulful pop-rock tune features sweeping melodies and strong vocals.
18. “Making the Most of the Night” by Carly Rae Jepsen
This pulsating track was written for Jepsen’s post-“Call Me Maybe” life and it definitely sounds more mature.
19. “Throw Down the Roses” by Kate Pierson
This song was written for the lead singer of the B-52s for her solo pro solo album in her 38-year career.
20. “Gentlemen” by Jessica Sanchez
Sia co-wrote this track for the “American Idol” runner up’s debut album in 2013.
