Fans might be shocked to find out what Billie Eilish's "Everything I Wanted" is actually about. As Pop Buzz noted, when talking to British radio presenter Annie Mac, the singer went into detail about the inspiration behind the single. "Pretty much that whole song is about me and Finneas' relationship as siblings," Eilish said. "We started writing it because I literally had a dream that I killed myself and nobody cared and all of my best friends and people that I worked with basically came out in public and said, like, 'Oh, we never liked her.' In the dream, the fans didn't care. The internet sh** on me for killing myself, all this stuff, and it really did mess me up."

Eilish went on to share that it's about how she knows she and her brother can lean on each other through thick and thin. "I mean, the message behind the song is like... my brother is my best friend, and I have these dreams and these things happen, and no matter what happens, he's gonna always be there for me and it's the same the other way around," she said.

The track, which has racked up over 172 million plays on YouTube and reached No. 8 on the Billboard Hot 100, contains undoubtedly dark themes, but it's also about the unbreakable bond of two siblings.
