Billie Eilish’s “Birds of a Feather” has flown to the top of Spotify’s list of biggest songs of 2024 with 1.775b streams.

The streaming service says that the breezy pop smash is its most streamed song of the past year. It’s from Eilish’s third album, Hit Me Hard and Soft, and was written by the 23-year-old and her other brother and collaborator, Finneas.

“Birds of a Feather” has peaked at No. 2 on Billboard’s Hot 100 chart and is spending its 21st week on top of the Hot Rock & Alternative Songs chart. It is nominated for three honors at the Feb. 2 Grammy Awards, including song of the year, record of the year and best pop solo performance.

“There’s a lot of songs about dying for somebody and loving them until they die, and I thought it was really fun to lean in,” Finneas said in a video on Eilish’s YouTube channel about the making of the track.    

Hit Me Hard and Soft is nominated for album of the year and best pop vocal album at the Grammys, while lead single “Lunch” is up for best music video and “L’Amour de Ma Vie [Over Now Extended Version]” is nominated for best pop dance recording. From 32 nominations, Eilish has won nine Grammys including two for both song of the year and record of the year. 

Finneas, 27, has won 10 Grammys out of 17 nominations. He’s the youngest person to ever be named producer of the year at 22 years old. He recently composed music for the Apple TV+ series Disclaimer and said working with Attacca Quartet on the music inspired him while making Eilish’s latest album.

“The real twin flame of this is that I was doing the TV show for the whole year that I was making Billie’s album, and so I had this in the back of my mind, always working on the strings. I would work on Disclaimer right before Billie would come over every day, then she’d leave, and I’d work on it again. And so I really credit Disclaimer for being the reason that there is a string overture in that album,” Finneas told The Hollywood Reporter.

“It is something we have always loved. The albums that we referenced while we were making this album were Sgt. Pepper and Abbey Road — they have these motifs that return, and so it was something we’d wanted to do. But I credit the show for giving me the learned experience of how to do it.”
