Billie Eilish's new single "Everything I Wanted" is an ode to her brother FINNEAS

The teenage superstar is back with her first single since releasing her debut album When We All Fall Asleep, Where Do We Go? in March.

"Everything I Wanted" is co-written by Eilish and her brother FINNEAS.

Speaking about the new release, Eilish explains, "This song is one my brother and I wrote about each other. No matter what happens, we always have been and will be there to make it better."

Last month she performed a small snippet of Elliott Smith's "Let's Get Lost" on Sirius XM's The Howard Stern Show.

Eilish was recently announced as a headliner for next year's Madrid's Mad Cool Festival.
