The American rock band My Chemical Romance has recorded over 90 songs during their career, which includes extended plays (EPs) demos, and covers. The band was formed in New Jersey in September 2001, and signed a contract with record label Eyeball Records, releasing their debut album, I Brought You My Bullets, You Brought Me Your Love, in July 2002. It is considered an emo, post-hardcore, punk rock, and pop-punk album, with additional influences from hardcore punk, heavy metal, and horror punk. The album's lyrics and themes center around depression and suicide, with some fans considering it to be a concept album, revolving around a story based on two lovers inspired by Bonnie and Clyde.

In August 2003, the band left Eyeball and signed a deal with Reprise Records. Their second studio album, Three Cheers for Sweet Revenge, takes influences from emo, alternative rock, pop-punk, post-hardcore, punk rock, and pop rock. It was released in June 2004 and features a more polished sound than their debut. Three Cheers for Sweet Revenge was originally supposed to be a concept album, serving as a continuation of the story of "Demolition Lovers", a song from I Brought You My Bullets, You Brought Me Your Love. Following the death of the characters, the duo would be separated, with one in heaven and the other in hell, only able to reunite if the male partner could harvest one thousand souls. However, Gerard Way revealed that his grandmother's passing resulted in the band wondering how they would tackle the concept, concluding that he would only write songs that he felt like writing.

Their third studio album, The Black Parade, was released in October 2006. It is a concept album that focuses on the story of a man dying of cancer, known as "the Patient", as he nears the end of his life and goes on a journey to the afterlife, reflecting on his life and the traumas that went along with it throughout his journey. The Black Parade is an emo, alternative rock, pop-punk, hard rock, punk rock, glam rock, progressive rock, and post-hardcore album, also including several influences from 1970s classic rock that had not previously been present on Three Cheers for Sweet Revenge. The album contains some of the band's most well-known songs, including "Welcome to the Black Parade", "Teenagers", and "Famous Last Words", often referred to as some of the best songs in the band's discography as a whole.

My Chemical Romance began to work on their fourth studio album in June 2009. Unlike the band's previous works, they wanted to create a "straight-ahead rock 'n' roll record" with no story or characters, and songs that worked better in party settings. Eventually, the band scrapped the project because they were unsatisfied with the result, and later released the scrapped recordings throughout 2012 to 2013 under the name Conventional Weapons. The band released their fourth studio album, Danger Days: The True Lives of the Fabulous Killjoys, in November 2010. Danger Days is a rock opera that is based around the fictional lives of the Killjoys, a group of rebellions living in a post-apocalyptic California in the year 2019. It includes elements of alternative rock, pop-punk, power pop, pop rock, glam rock, and electronic rock. After the band completed touring for Danger Days, they began to work on their fifth studio album in early 2012, with the working title The Paper Kingdom. The Paper Kingdom was intended to be a concept album, telling the story of a support group of parents whose children had died, and would make up a narrative about how their children were lost in the woods fighting against a witch. The band would later breakup in March 2013, leaving The Paper Kingdom left unfinished. One of its intended songs, "Fake Your Death", was later included in the band's greatest hits album May Death Never Stop You (2014), promoted as the band's final song.

After announcing their reunion in 2019, My Chemical Romance returned with "The Foundations of Decay" in May 2022. Its composition was praised by several critics, with its lyrics reflecting on the band's origins and legacy. Musically, the song incorporates elements from doom metal, basement punk, arena rock, post-metal, metalcore, and noise rock, having been compared to ones found on I Brought You My Bullets, You Brought Me Your Love. In July 2025, during their Long Live The Black Parade tour, My Chemical Romance performed an unreleased track from The Paper Kingdom, titled "War Beneath the Rain".
