Billie Eilish joins star-studded Barbie soundtrack with song What Was I Made For

Billie Eilish is the latest musician to join the star-studded lineup on the soundtrack for the upcoming Barbie movie.

The Ocean Eyes singer, 21, announced her song What Was I Made For on Instagram on Thursday.

‘AHHHHHHHHHHHHHHHH!!! ‘What Was I Made For?’ COMING OUT JULY 13TH AT 7AM PT. !!!!!!!! 

‘WE MADE THIS SONG FOR BARBIE AND IT MEANS THE ABSOLUTE WORRRRLLLD TO ME. THIS MOVIE IS GONNA CHANGE UR LIVES AND HOPEFULLY THE SONG WILL TOO. GET READY TO SOB @FINNEAS,’ she excitedly captioned the post.

The Bad Guy singer – who admitted she was hurt by body shamers –  joins Ava Max, Charli XCX, Dua Lipa, Gayle, Haim, Ice Spice, Karol G, Khalid, Lizzo, Nicki Minaj, Tame Impala and more on the Mark Ronson-produced soundtrack.

Billie’s song will be the sixth single to be released from the soundtrack after Nicki Minaj and Ice Spice’s Barbie World, Charlie XCX’s Speed Drive, Dua Lipa’s Dance the Night, Karol G’s Watati and PinkPantheress’ Angel. 

The Barbie soundtrack is due out on July 21 – the same day as the movie’s theatrical release.

Ronson, 47, has worked with some of the biggest names in music over the years and he jumped at the chance to oversee Barbie: The Album. 

‘Those two make some of my favorite films,’ he told Time about co-writers Greta Gerwig and Noah Baumbach 

‘I thought, “Even if I don’t get this gig, I know this is going to be my favorite movie next year.”’ 

He and Gerwig, 39, hit it off right away. ‘I became the Robin to her Batman,’ he said.

Gerwig sent Ronson a list of music she loves, which he called ‘guilty pleasures’ and ‘Peloton pop.’

And along the way, he found out many of the musicians were drawn to the soundtrack because of their own histories with Barbie – including Eilish.

‘One of the artists is obviously one of the f***ing greatest living artists around but also had a very personal, idiosyncratic tie to Barbie as well,’ he teased of Eilish’s involvement. 

‘Karol G was instantly telling us how much Barbie meant to her,’ Ronson explained.

Barbie World: Ronson detailed the process of including Aqua’s iconic song Barbie Girl in the movie without the band’s involvement after they made it clear they didn’t want to do it

Fever dream: Instead, he recruited Nicki Minaj and one of the hottest artists of the moment, Ice Spice, to sample Aqua’s song and called it Barbie World. Ronson calls the track ‘a fever dream of an incredible song,’ and Aqua is credited on it as co-writers and performers

‘I thought everyone was here because Greta Gerwig is making this awesome movie, and there’s been all this buzz around it,’ but he soon realized that ‘This [film] was really important to a lot of people.’
