I wanted to do something about Plutonia because it has a unique tracklist but it just reuses music from Doom and Doom 2. When the time's right I might come back and ask if you can include one of these. At the very least better instructions are needed. Once things are in a better state I want to try to streamline the process.

I do appreciate that this makes things slightly more complicated to set up, though. So you can play a WAD file like Suspended in Dusk, for example (which uses a bunch of IWAD tracks for its levels), and you'll hear the high-quality SC-55 tracks. The advantage of doing it this way is that even if you have PWADs containing MIDI tracks from Doom, they'll be detected and replaced correctly. The SHA1 hash uniquely identifies the MIDI lump based on its content: if the lump contains that exact data, the replacement file will be used. The right part is the filename to use, and on the left is a SHA1 hash of the MIDI it's replacing. I have a set of example files for each game Chocolate Doom supports. The short summary is that you need a substitution config file.

It's probably best to leave it off the list for now, though it is possible to get working. I need to put together some proper instructions about how to set this up, and of course get it running on Windows. If there was a set of instructions I could post I could add it again with a note saying it doesnt yet work in Windows. I used to list it as supported with metadata loop tags but I got emails asking me how it's done and I, well, don't know! So I removed it from the list. That's great to hear about Chocolate Doom! I'm still fuzzy on how it's implemented, though.
