Getting Older

"Getting Older" is a song by American singer-songwriter Billie Eilish and the opening track of her second studio album, Happier Than Ever (2021). Featuring a minimalist production, the song is backed by pulsing synthesizers, a bass guitar, and a keyboard that plays staccato notes. Its lyrics discuss the positive and negative aspects of Eilish's transition into adulthood in the wake of her success that she first received as a teenager. Due to the subject matter, critics compared the song to Nirvana's "Serve the Servants", the opening track of their 1993 studio album In Utero. "Getting Older" contains references to sexual abuse and Eilish's childhood trauma, prompting her to take a break midway through the writing process.

Many music critics deemed the song a powerful opening track, and some applauded its relatability despite the difficulties of writing a song about fame that resonates with laypeople. They argued that this was achieved through references to universal, sympathetic experiences, such as feeling burdened by large amounts of expectations and horrified by the loss of one's childhood. Upon Happier Than Ever's release, "Getting Older" charted in 14 countries and reached the top 40 of 5 national charts. It peaked at number 69 on the US Billboard Hot 100 and number 35 on the Billboard Global 200. Eilish starred in a 2021 concert film and embarked on a 2022–2023 world tour in support of the album; the song was included in their respective set lists. American singer Adam Lambert made a glam rock rendition of the song for his fifth studio album High Drama (2023).
