Background: Good Charlotte is an American rock band from Waldorf, Maryland, that formed in 1996. Since 1998, the band's constant members have been vocalist Joel Madden, guitarist and vocalist Benji Madden, bassist Paul Thomas, guitarist and keyboardist Billy Martin, while drummer Dean Butterworth has been a member of the band since 2005. After a four-year-long hiatus, the band announced its comeback on November 3, 2015. The band has released six studio albums: Good Charlotte (2000), The Young and the Hopeless (2002), The Chronicles of Life and Death (2004), Good Morning Revival (2007), Cardiology (2010) and Youth Authority (2016), as well as two compilations: Greatest Remixes (2008) and Greatest Hits (2010).
Context: Good Charlotte's third album, The Chronicles of Life and Death, was released by Epic Records in 2004. The album received mixed reactions from both the music press and Good Charlotte's fan base. The album sold 2.2 million copies. The album has been widely considered a departure from the band's previous two albums, mixing new elements such as lyrical topics into Good Charlotte's youthful sound. Singles released from the album include the two hits "Predictable" and "I Just Wanna Live", as well as "The Chronicles of Life and Death" and "We Believe". The only single from The Chronicles of Life and Death which managed to chart on the U.S. Hot 100 was the hit "I Just Wanna Live". All of the singles released from the album went top 30 in the UK, except for "We Believe". The band would then go on tour with Sum 41.  In May 2005, after much speculation from fans, it was officially confirmed that Chris Wilson had left the band citing personal health reasons. Benji also told Kerrang! magazine that, for him, "Chris leaving the band was the worst part of 2005." Chris then joined the pop/punk band The Summer Obsession until 2011. He currently plays drums for JMSN.  On Good Charlotte's "Noise to the World" Tour, performing with Simple Plan and Relient K, the band recruited Dean Butterworth (who had previously played for Morrissey) as the band's temporary drummer. Later, in March 2007, Butterworth was confirmed as the band's permanent drummer.  Benji Madden has claimed in interviews that he feels this record was not as successful as the previous record due to it being "too selfish."
