Definitely not in the case of the MP3. That was made by me using LAME, via
foobar2000. I don't even have FhG on any of my computers.
I don't recall the Blaze file being 192, either--bitrate is selectable from
a menu and I thought I selected 128 CBR. But I'd have to double check.
I don't have the mp3s handy on this computer, and the badongo downloads have
expired.

There is no remastered version of Decade.
