This could be an example answering a frequently asked question, I am not sure which though:
Have a look at Disc 2, Track 5, The Great Gig in the Sky. Possible hypotheses:
- TGGitS is a track that half of us hate and deliberately omit,
- There are production differences at track level, which might explain that a single track exhibits weird results.
I'd rather lay my money down on the second of these, but Spoon: Is it possible for you to look up this particular disc and see if it is so that there is a matching entry for this track with AR around sixty?
(Of course you might hypothesize that TGGitS is a track that someone loves so much that (s)he did sixty different rips of his Pulse CD in order to have an accurate rip, hence every other track has that much higher score. That's why I included Disc 1 )
