Must-listen: Billie Eilish's James Bond theme song 'No Time To Die'.

Billie Eilish has shared her highly-anticipated theme song to the upcoming James Bond film, titled 'No Time To Die'.

The song was produced by her brother Finneas, alongside Stephen Lipson, with orchestral arrangements by Hans Zimmer and Matt Dunkley, and guitar from Johnny Marr.

About being part of the soundtrack, Eilish says: “It feels crazy to be a part of this in every way. To be able to score the theme song to a film that is part of such a legendary series is a huge honour. James Bond is the coolest film franchise ever to exist. I’m still in shock."

Billie will perform the song with Finneas, Hans Zimmer, and Johnny Marr for the first time at the Brit Awards in London on February 18th.
