This torrent link included FLAC rips of each BGM release for the Micron/Unicron trilogy, but it is long dead, and all other rips of these albums I could find were at pretty low bitrates. I was wondering if anyone had picked this up in the past and would be willing to share (or link me if there's an active link with thread somehwere here on the forums), though I would also be satisfied with 320k links as well, as those would still be great improvements over the 128-192k rips I've found.

I managed to download the torrent, albeit with an extended period of time of a few days. It's likely you can as well if you just leave it in your torrent client while going about your business.
