My Heart Will Always Be The B-Side To My Tongue

My Heart Will Always Be the B-Side to My Tongue is the first EP by American rock band Fall Out Boy. It was released on May 18, 2004 through Fueled by Ramen as a Digipak while the band was recording their major label debut album From Under the Cork Tree (2005) for Island Records. The CD is packaged with a bonus DVD, featuring the background of the band, music videos for "Dead on Arrival" and "Grand Theft Autumn/Where Is Your Boy", an acoustic performance and more extras. The CD features a total of five tracks; two new acoustic songs, two acoustic versions, and a cover.

"Grand Theft Autumn/Where Is Your Boy" was re-recorded as an acoustic version, from the previously released version from the band's 2003 album, Take This to Your Grave. The album version of "Nobody Puts Baby in the Corner" appears on the band's third album From Under the Cork Tree, and a demo of "My Heart is the Worst Kind of Weapon" with rock music instrumentation is featured on the From Under the Cork Tree (Limited "Black Clouds and Underdogs" Edition). A cover of the Joy Division song "Love Will Tear Us Apart" is also included. There is also hidden footage of the band on the eye of the angel in the main menu.

The EP debuted at No. 153 on the Billboard 200, Fall Out Boy's first entry on that chart (their next entry week would be at No. 9 with From Under the Cork Tree). It also peaked at No. 5 on the Billboard Heatseeker Albums and No. 10 on the Billboard Independent Albums. The artwork was designed by Jacob Bannon, vocalist of the hardcore band Converge.
