I am making a new post so this bubbles up in newsfeeds again.
There was a problem with the FLAC encoding in the original R.E.M. Strand Cabaret '82 fileset. Songs were weirdly skipping mid-song direct to the next song, and it was completely reproducible on my end with the original files.
I re-encoded to FLAC without errors this time, and re-uploaded the files.
The corrected fileset is now the one accessible in the links in the original post. So, please go to the original post and re-download the set; it's well worth the trouble.
