Judging by the first 10 minutes of the game, it does, mostly!
I installed the
T-Edition MSU-1 patch, which patches the ROM to add the new music for the T-Edition in PCM format. That gives you a bunch of PCM files with names like [ROM name]-37.pcm. These are, for the most part*, new tracks and don't overlap with the tracks from other MSU-1 patches. So I just copied all the PCM files out of the Pixel Remasters zip file into the same directory as the ROM and the other PCM files, and so far they mostly seem to work fine with the T-Edition MSU-1 patch.
When I say "mostly", I've played through to the first save point, and so far the title screen, intro, opening credits, and battle themes all work correctly. (And the victory fanfare is just the stock cartridge version, not MSU-1.)
The wrong music started playing when I entered the mines. Different music than usual started playing when I entered the mines, but I looked up a T-Edition playthrough video and apparently it's supposed to do that.When I reset after saving, the Prelude played correctly on the load screen but continued to play after I loaded my game. Other than that, no issues so far.
I can't speak to the T-Edition differences just yet except that you can hold down B to dash and Biggs and Wedge have the full set of Magitek abilities just like Terra. And there's a music player if you go to the Config menu and hit the A button on Sound. Which is useful for confirming that yep, both sets of PCM tracks are working.
So I'm not an expert on how MSU-1 patches work but from poking around a little with the patch my guess is, if there's a music prompt, it searches for the corresponding numbered PCM file and if it's there, it plays it, and if it's not, it falls back to the chiptune. I think that's why you can add PCM files that aren't included in the T-Edition MSU-1 patch and it'll play them, and in the correct place.
* tracks 56, 101, 102, and 103 overlap with track numbers from other MSU-1 patches. I can't get the PCM files to play in VLC so I don't know for sure what they are. I'm guessing since 101-103 are the last 3 tracks included with the Pixel Remasters music patch that they're the ending music, but I don't know what 56 is. My first guess was the opera, but it doesn't seem to be that, at least not any of the voiced parts, as the Pixel Remaster patch includes three tracks that are available in multiple languages which presumably correspond to the opera singing, and those are 39, 66, and 69.
