The Warrior's Code is the fifth studio album by the Irish-American Celtic punk band, the Dropkick Murphys. Released in June 2005, it is also their bestselling. It features a dedication to Lowell's own "Irish" Micky Ward who is featured on the album's cover and is the subject of the album's title track. It is also their final record with Hellcat Records before moving to their own vanity label, Born & Bred Records. The album features one of the band's biggest and most well known singles, "I'm Shipping Up to Boston", which the band originally released on the "Fields of Athenry" single, although it re-recorded it for The Warrior's Code. The band released the song on their own as a single in 2006. However, it became a hit after being featured in the Oscar-winning movie The Departed and its soundtrack. The band filmed music videos for "Sunshine Highway", "The Warrior's Code" and two videos for "I'm Shipping Up to Boston", the second was used for The Departed. A video for the track "Tessie" was also filmed in 2004 when the song was released as its own single.
