: As for the tracks you've provided, these were released for free officially at
: some point, indeed. They do deserve to be archived, but I believe you're
: misinformed in places.

yeah I was just corrected on that

: I also believe the ODST tracks are identical to their OST counterparts. For
: example, let's take "Prepare to Drop". It's the same as the
: ending portion of "Finale" in the ODST OST. As for
: "Rain" - that is the official name of that portion of Deference
: For Darkness (not "difference").

That's what I thought it was for years but then I saw some official thing calling it "Difference for Darkness". Where's your source for the name?

: Deference For Darkness is a suite of tracks. Rain is the name of that beginning piano portion of it.
: ODST Theme is essentially being the E3 2009 version of the track, which
: was more or less just a portion of "Finale."

: Halo 3 E3 2007 is interesting, though. I also have this, and it's more or
: less a remix of One Final Effort.

: Reach is the most interesting stuff. Ashes piano and Ghosts and Glass piano
: are effectively stems of the official tracks featuring only the piano
: portions. Already had these though. Lone Wolf is the VGA trailer version,
: but sounds more or less identical to that portion of Winter Contingency. I
: have two additional promotional Reach tracks aside from those you've
: provided. These would be "Lone Wolf Ringtone" (shorter - meant
: for a looping ringtone) and "Noble Map Pack Trailer Music" (A
: remix featuring all Bungie's Halo themes).

: As for "unknown Halo 4 music" - It's definitely a portion of
: Arrival, but it's not identical. Sounds like a lower quality, muted
: version of the full thing, as if it's a background track, or a teaser of
: some sort. I wasn't following Halo 4 development enough to spot that, so I
: don't know the context for it.

OK, thanks
