It's possible to do it in zDoom and it might be possible in Doomsday (though i don't know how).

In order for mp3 music to play in zDoom:
1: Rename the song to a simple and short name (keep mp3 extension)
2: Import it into the map's wad file (tha's called pwad i think) with a wad program like XWE
3: Create a new lump in the wad named "MAPINFO" and insert:
map E1M1 "Fancy Map Name Goes Here"
music BLORGH
(BLORGH = replace this wid the name of the mp3 file, but DON'T add the mp3 extension)
(E1M1 = replace this with the name of the map lump)

However, making a WAD port-specific solely for the sake of having MP3-quality music is a bit unnecessary, in my opinion. Vanilla Dooms all support custom MIDIs--all you have to do in this case is rename the MIDI to the name of the music that was originally used for the map slot you are using (for example, the name for MAP01's music was D_RUNNIN--there's a list or two of the names to change them to somewheres but I can't find it at the moment) and add it to the WAD using a program such as XWE, and it will automatically replace the map's original music.

And were could I find free to use mp3 music.
