The powerful music video, directed by Petra Collins, showcases Rodrigo as a cheerleader seeking revenge on her ex-boyfriend, earning acclaim for its portrayal of teenage angst.

Praised by critics for its honesty and catchy melody, “Good 4 U” achieved commercial success, topping the Billboard Hot 100 chart in the United States and setting streaming records for a female artist’s debut week. The mid-tempo pop-punk sound, driven by electric guitars, drums, and piano, complements the song’s raw emotion. The title, “Good 4 U,” signifies her ex’s seemingly thriving post-breakup, while she struggles to move on. Rodrigo candidly expresses her feelings about her ex-partner moving on swiftly, leaving her feeling unimportant. Released as the third single from her debut album, “SOUR,” on May 11, 2021, the song captures the emotions of anger and resentment after a breakup. She plays the role of a high schooler out for revenge, destroying the bedroom of her former boyfriend and lighting his belongings on fire.Good 4 u is a compelling English-language pop-punk anthem by Olivia Rodrigo, co-written with Josh Farro, Hayley Williams, and Dan Nigro, and co-produced by Nigro and Alexander 23. In the video, Rodrigo appears in a variety of looks, including a cheerleading uniform seen in 2001 coming-of-age film The Princess Diaries (also seen in the cover artwork). Rodrigo was styled by vlogger Devon Carlson for the video. The music video references horror films such as Audition (1999) and Jennifer's Body (2009). On May 15, 2021, actress and the star of Netflix's Stranger Things, Millie Bobby Brown posted on her Instagram story of her lip syncing to Rodrigo's single in front of a bathroom mirror with the caption thanking Rodrigo and stating she's a "legend."Īn accompanying music video directed by Petra Collins was released alongside the song on May 14, 2021. In agreement, Halle Kiefer of Vulture also named the song an "angry track" evocative of "Misery Business" in "the best possible way" and writing for People, Tomás Mier has described the song as a "heartbreak track filled with an angsty pop-rock sound." Sydney Bucksbaum, writing for Entertainment Weekly, called the single a "pop-punk breakup anthem" and an "immediate banger", underlining the song's similarities to Paramore's "Misery Business" (2007). Dodson found Rodrigo's voice versatile, easily moving between styles similar to Swift's vocals in "We Are Never Ever Getting Back Together" (2012), and that of Alanis Morissette and Hayley Williams, to become "something original". Teen Vogue's Claire Dodson said that "Good 4 U" gives "pure 2000s pop-punk" aside Rodrigo's "knockout songwriting". Variety critic Ellise Shaffer dubbed the song a "nostalgic heartbreak anthem" evoking a "fluttering, cathartic feeling reminiscent of late '90s Hole or early Paramore, but with a poppier flair". Rob Sheffield of Rolling Stone lauded Rodrigo's musical versatility, and noted influences from Taylor Swift in "Good 4 U". It marks a departure from Rodrigo's preceding singles, "Drivers License" and "Deja Vu", which presented a melancholic and slower emotion. Lyrically, Rodrigo confronts a former love interest in the song who has moved on very quickly from their relationship, using plentiful sarcastic remarks. The second verse returns to the original bass line with added "lilting" drum beats and backup harmonies, and slowly ascends to Rodrigo's "near-shout" vocal delivery.

The song begins with a staccato bass line and Rodrigo's vocals delivered in a soft tone, which is then joined by an energetic guitar before dropping into the drums-driven chorus. It was written by Rodrigo and Dan Nigro, and produced by Nigro and Alexander 23. Its instrumentation is driven by a set of 1990s-inspired electric guitars and bass.

"Good 4 U" is a pop-punk, grunge, pop rock, and teen-pop song with alternative inflections. Rodrigo had previously teased the song in a promotional image for "Deja Vu". Alongside the announcement, she also revealed the song's cover artwork. On May 10, Rodrigo announced via her social media accounts that "Good 4 U" would become the third single from Sour on May 14, following "Drivers License" and "Deja Vu". "Good 4 U" placed sixth on the track listing. Rodrigo announced her debut studio album Sour on April 1, 2021.
