Doom music

All of Doom's music was composed by Robert Prince. The new episode added in The Ultimate Doom did not add any new tracks and only used songs from the first three episodes.


 * 1) The inspirations for the tracks noted above are substantiated by metadata comments found in the  released by John Romero, many of which are alternate versions of the MIDI tracks used in Doom. See the article: Musical inspirations behind Doom's music.
 * 2) The Doom IWAD file includes two title screen MUS lumps, d_intro and d_introa.  The latter is used when using OPL MIDI playback (ie. on an Adlib or Soundblaster card).

!Lump names!!Size!!CRC-32 Of all the above Doom songs with different versions, "Waltz of the Demons" is the only one with an audible difference: the bass string instrument that comes in at about 10 seconds in is quieter in D_E2M7 than in D_E3M7. (MIDI channel volumes of 80 and 100, respectively.) The other songs have slightly different MIDI data between versions, but nothing that causes a difference in the way they are played.
