On Thursday, Billie Eilish debuted a new track called “Therefore I Am”.

The song was released just four months after her latest track, “Everything I Wanted”.

Back in October, Billie answered fan questions on Instagram. When one fan asked, “NEW SONG?????”, the singer responded in tiny script, “november”, followed by a shushing emoji.

When another fan asked, “give us a color that matches the song coming in November”, the 18-year-old responded with a shade of burnt orange. That colour later became the inspiration for the album artwork.
