So I think I have an idea of what happened, this may be a pretty big encoding bug on their part, I think they actually intended all files to be around 100kbps, because the blocks I recovered at the end of that file actually do appear to be at that bitrate, but for some reason, who knows, due to some encoder bug or game decoding issue, that data was then overwritten by a lower quality stream of only 67kbps, and this bit at the end with the last bit of the song may just be a leftover of what it was originally going to be quality wise, which is pretty sad if my theory here is correct... When comparing the bit at the end and a theoretical "overall" bitrate of the file, if it was all used that is, they would work out to be about the same.
edit: oh also its 64kbps to be perfectly exact here, because each block starts with 8 "header" bytes, subtracting those works out to exactly 64kbps cbr. The actually intended size was actually 96kbps cbr but it was seemingly overwritten at some point...
