The band reunited with Save Rock and Roll (2013), which became Fall Out Boy's second number-one album, and included the top 20 single "My Songs Know What You Did in the Dark (Light Em Up)".

The band's sixth studio album, American Beauty/American Psycho (2015) peaked at number one on the Billboard 200, and spawned the top-10 hit "Centuries" and the single "Uma Thurman" which reached No.

[13] Kunasch was temporarily replaced by friend Brandon Hamm on guitar, alongside drummer Chris Envy from the recently disbanded Showoff, but both quit prior to the kickoff of the tour.

"[12] John Janick of Fueled by Ramen had heard an early version of a Fall Out Boy song online and cold-called the band members at their apartment, first reaching Stump and later talking to Wentz for an hour.

"[16][17] As the band progressed and the members' roles became more defined, Wentz took lyrics extremely seriously in contrast to Stump, who had been the group's primary lyricist up to that point.

Two weeks before recording sessions began, the group abandoned ten songs and wrote eight more, including the album's first single, "Sugar, We're Goin Down".

[26][29][30] It was spearheaded by the band's breakthrough single, "Sugar, We're Goin' Down", reached number eight in the US Billboard Hot 100 in September 2005, and in the UK chart in February 2006, crossing over from Alternative to Pop radio.

[23] The band performed at music festivals in 2005 and 2006, including the third Nintendo Fusion Tour in the fall of 2005, joining The Starting Line, Motion City Soundtrack, Boys Night Out, and Panic!

[31] He gained additional exposure through his clothing line, his Decaydance record label (an imprint of Fueled by Ramen), and eventually a celebrity relationship with pop singer Ashlee Simpson, which made the two tabloid fixtures in the United States.

[23][31][34] Due to its increased success from the group's MTV Video Music Award, Fall Out Boy headlined the Black Clouds and Underdogs Tour, a pop-punk event that featured The All-American Rejects, Hawthorne Heights, and From First to Last.

[35] After taking a two-month-long break following the band's Black Clouds and Underdogs tour in promotion of From Under the Cork Tree, Fall Out Boy returned to the studio to begin work on a follow-up effort.

[64] Sessions proved to be difficult for the band; Stump called the making of the album "painful", noting that he and Wentz quarreled over many issues, revealing "I threw something across the room over a major-to-minor progression.

[67] To promote the album, Wentz launched a viral campaign in August 2008, inspired by George Orwell's novel Nineteen Eighty-Four (1949), and the autocratic, overbearing Big Brother organization.

[71] Within two months of its release, Folie à Deux was certified Gold in the United States by the Recording Industry Association of America (RIAA), denoting shipments of 500,000 copies.

[73] The lead single, "I Don't Care", reached a peak at number twenty-one on the Billboard Hot 100,[74] and was certified two-times Platinum by the RIAA for shipments of two million copies.

[82] Near the end, Blink-182's Mark Hoppus shaved Wentz's head in a move Andy Greene in Rolling Stone later described as a "symbolic cleansing of the past, but also the beginning of a very dark chapter for the band".

[84] Previously known as the "overexposed, despised" leader of the band, Wentz "simply grew up", sharing custody of his son and embracing maturity: "There was a jump-cut in my life.

Stump revealed that fans harassed him on his solo tour, hurling insults such as "We liked you better fat", and noted that "Whatever notoriety Fall Out Boy used to have prevents me from having the ability to start over from the bottom again.

[87] He also formed heavy metal outfit The Damned Things with Trohman, Scott Ian and Rob Caggiano of Anthrax, and Keith Buckley of Every Time I Die.

Inspired in part by Daft Punk's Interstella 5555: The 5tory of the 5ecret 5tar 5ystem, the band released a music video for every song on the album in a series titled The Young Blood Chronicles between February 2013 and May 2014.

[106] Fall Out Boy headlined Save Rock And Roll tours (including US, Australian and European legs) and played at music festivals around the world for one and a half years.

[182][183] The same day, guitarist Joe Trohman announced publicly on social media that he would be taking a break from the band to focus on his mental health, but stated that he intended to return.

[201] On February 28, 2024, the band released a music video for the album's fourth single, title track "So Much (For) Stardust", featuring NBA player Jimmy Butler.

[29] Lead singer Patrick Stump, however, is also influenced by a wide variety of bands and artists, including Elvis Costello, Pantera guitarist Dimebag Darrell,[235] Prince,[236] Michael Jackson,[236] and David Bowie.

[237] Fall Out Boy's albums Take This to Your Grave and From Under the Cork Tree are both said to have pop-punk as well as punk rock sounds and influences,[238][239] and Infinity on High features a wide range of styles and instrumentation, including orchestral arrangements ("Thnks fr th Mmrs"[240]) and a slower piano ballad ("Golden").

[244] The group has worked with many producers and artists, including The Neptunes, Timbaland, Ryan Adams, Lil Wayne, and Kanye West, the latter of which Patrick Stump described as "the Prince of his generation".

[253] Sarah Jamieson of DIY, wrote that, "[the album] sounds closer to...their 2008 record Folie à Deux than 2018's...Mania, there's a return to the bold, luscious pop-rock that they honed early on.

[256] A central part of Fall Out Boy's sound is rooted in the band's lyrics, mainly penned by bassist Pete Wentz, who commonly uses irony and other literary devices to narrate personal experience and stories.

"[234] He draws inspiration from authors such as Charles Bukowski, Ernest Hemingway, and JT LeRoy, as well as rappers such as Lil Wayne, who he described as his primary influence while writing Infinity on High.

[265] This honor is given to artists who have used MTV Woodie Awards as a "launching pad" in achieving chart topping success within their musical careers, thus influencing up and coming bands.
