Metallica's debut album, 'Kill 'Em All,' hit storeshelves on July 25, 1983. It would lay the foundation for the future of the band's success, both as a thrash metal band and as one of the biggest acts in the history of music. Recently, songs like 'Seek & Destroy' and 'Hit the Lights' have become staples at Metallica concerts, but back when the album was first released, there were two other songs that initially made big splashes in the rock world.

As the first single released from 'Kill 'Em All,' 'Whiplash' could easily be considered an anthem for headbangers across the world. With intense lyrics like 'Bang your head against the stage like you never did before / Make it ring, make it bleed, make it really sore,' the song displays the ferociousness of Metallica's thrash roots. 'Whiplash' was released as a U.S. single on Aug. 8, 1983.

The second and final single released from the album was 'Jump in the Fire,' a tune that drummer Lars Ulrich has said was inspired by Iron Maiden's 'Run to the Hills.' Continuing the intensity of 'Whiplash,' James Hetfield altered Dave Mustaine's original lyrics from a sexual theme to a more devilish theme. The song focuses on Satan watching people do things that doom them to Hell. 'Jump in the Fire' was released internationally on Jan. 20, 1984.
