The original game's soundtrack made by Bobby Prince was popularly associated with, a novelty for videogames at the time, but also approached other styles for specific tracks. Over the years, many composers added their own musical interpretation to the series.

Classic Doom
All of the music in Doom and Doom II was created by Bobby Prince. Initially, John Romero gave a couple of heavy metal records and told him to create something similar for Doom. Prince created the rock-oriented tunes and also composed some more ambient tracks since he felt that heavy metal might not be appropriate for the entire game. Many of these songs were inspired by or closely mirror popular rock and metal songs from groups such as Slayer, Metallica, Megadeth, Pantera, AC/DC, Alice in Chains, and Black Sabbath.

In Final Doom, the new music was created by Jonathan El-Bizri, Josh Martel, Tom Mustaine, and L.A. Sieben.

Aubrey Hodges
The music in Doom and Final Doom for Sony PlayStation, and in Doom 64 for the Nintendo 64, was composed by Aubrey Hodges and differs greatly from the original PC songs. More focused on sound textures than regular songwriting, Hodges composed a soundtrack of eerie and atonal meant to go along with the darker style of these games and increase a sense of fear with the player. When Quake was released for the Nintendo 64, it featured music identical in style to that of Doom 64, going so far as to use the same samples. The version of Doom for the Sega Saturn additionally reuses Hodges' PlayStation soundtrack.

Doom 3

Trivia

 * Virtually all of the music in Doom and Doom II follows the structure.
 * The music inside the Doom engine's IWAD files is not stored as MIDIs, but as MUS, a format similar to MIDI created by Paul Radek for DMX. However, PWADs may contain actual MIDI files since the Doom engine obtained MIDI file support in v1.5. In addition, all source ports support MIDI natively and have to convert MUS lumps back to MIDI.
 * Although most gamers at the time had more affordable FM OPL based or  sound cards, Doom and Doom II was composed on the  sound module. Support in the engine exists for OPL2-based and Gravis Ultrasound cards, in addition to generic General MIDI output. Native  support was added in 1.4.
