Billie Eilish is the daughter of home-schooled parents, who encouraged her to pursue her passions outside of the traditional education system. She grew up singing and dancing and making homemade films.

The singer is a songwriter and composer, and has released two studio albums to date. She has also become an award-winning artist and the subject of her own documentary.

'Happier Than Ever' is the title track of her sophomore album, which was released on July 30th. It was written by Eilish and her brother Finneas Baird O'Connell, who performs as FINNEAS.

It is a power ballad, which starts off with a ukelele accompaniment and eventually transitions into a distorted rock anthem midway through. The song is very cathartic and Eilish says that it was probably the most therapeutic song she's ever written.

She wrote the song when she was in her junior year of high school and it is one of the first songs that she wrote for the album. She said that it is about how her past love betrayed her and she is happier than ever without them in her life now.

The music video for the single has a similar tone to its lyrics, as it opens with Eilish wandering around in a glamorous room and then singing into a vintage telephone. The lights flicker halfway through the video and water floods the house, which leads to a dramatic ending as Eilish belts the track on the roof in the rain.
