List of songs recorded by Trivium: Trivium is an American heavy metal band from Orlando, Florida.

Metal Health: Metal Health is the third studio album by American heavy metal band Quiet Riot.  It was released on March 11, 1983, bolstered by the No. 5 hit "Cum On Feel the Noize" and the No. 31 hit "Metal Health".  "Metal Health" is notable for being the first heavy metal album to reach the top spot on the "Billboard" 200, replacing the Police's "Synchronicity" at number one in November 1983.  The album went on to sell more than six million copies and is considered a classic among heavy metal fans.  Some critics, such as AllMusic, describe it as a one-hit wonder, owing to Quiet Riot's relative lack of critical and commercial success with following albums (and subsequent disintegration) towards the end of the 1980s.  The title track was ranked No. 35 on VH1's 40 Greatest Metal Songs.

Kill 'Em All: Kill 'Em All is the debut studio album by the American heavy metal band Metallica, released on July 25, 1983, by the independent record label Megaforce Records.  "Kill 'Em All" is regarded as a groundbreaking album for thrash metal because of its precise musicianship, which fuses new wave of British heavy metal riffs with hardcore punk tempos.  The album's musical approach and lyrics were markedly different from rock's mainstream of the early 1980s and inspired a number of bands who followed in similar manner.  The album did not enter the "Billboard" 200 until 1986, when it peaked at number 155, following Metallica's commercial success with its third studio album "Master of Puppets"; the 1988 Elektra reissue peaked at number 120.  "Kill 'Em All" was critically praised at the time of its release and in retrospect, and was placed on a few publications' best album lists.  It was certified 3× Platinum by the Recording Industry Association of America (RIAA) in 1999 for shipping three million copies in the United States.  The album generated two singles, "Whiplash" and "Jump in the Fire".
