as introduced in DoomMetalVol5.wad.

Taken from Crispy Doom.

Just downloaded DoomMetalVol5 and it doesn't sound good 😄

We can use TRAKINFO for this, extras.wad already has records for Final Doom.

Optionally, given the possibility of having a built-in TRAKINFO generator (#2132), a possible woof.pk3:DoomMetalVol5.wad/TRAKINFO could be made to load these automatically, as well.

Well, that's a matter of taste. I prefer Metal über alles. 😁

So, we could place a TRAKINFO lump in the autoload directory for tnt.wad/plutonia.wad or for doommetalvol5.wad?

I will try the doommetalvol5.wad directory tomorrow.

TRAKINFO is not convenient for this, because the music file names in DoomMetalVol5.wad are the same as the MIDI names in IWAD. Okay, I guess we can hardcode it.
