"Judas Priest" was named as a tribute to the heavy metal band Judas Priest, and contains a bridge that references several well-known Priest songs. "The Constant" is about the episode of the 2004 television series "Lost" of the same name, where a character travels through time until he finds his "constant". "I'm Alive" was written when Dan Nelson was member of the band. Anthrax premiered the song live in 2008, though it was titled "Vampires" at that time. It is notable for its tribal-sounding introduction with clean guitars backed up by a marching drum beat, before taking off into a heavy riff and gradually breaking into a melodic chorus. In an album preview by Blabbermouth.net, "I'm Alive" was described as "beautiful and grand with a build that demands audience participation". The song was nominated for a Grammy Award in the category Best Hard Rock/Metal Performance, the band's fourth Grammy nomination. "Worship Music" was internationally released on September 12, 2011, and on September 13 in the United States. It sold 28,000 copies in the United States in its first week of release and debuted at number 12 on the "Billboard" 200, the third highest position of their career (the second being its successor, "For All Kings", which charted at number 9) and the highest since "Sound of White Noise" (1993), which peaked at number 7. The band's previous studio album, "We've Come for You All" (2003), opened with just under 10,000 units to debut at number 122. The album charted at number 13 in Germany and managed to break into the top 10 in Finland, reaching number 6. By September 2012, "Worship Music" sold about 100,000 copies in the United States. When asked about a possible follow-up to "Worship Music", bassist Frank Bello said that the band intended to re-release "Worship Music" with several bonus tracks. The bonus tracks were set to include covers of Rush and Boston songs. Bello stated that the plan was to release the reissue in the fall of 2012. A few days later, band members announced that five covers were included: "Anthem" by Rush, "Smokin'" by Boston, "Neon Knights" by Black Sabbath, "T.N.T." by AC/DC, and "Keep on Runnin'" by Journey. Although Scott Ian expected the reissue to be released by the end of the year, it was eventually postponed for 2013.
