The five are: the original American Mercury pressing, the UK RCA early '70s reissue, the Japanese late '70's reissue, the Rykodisc digitally remastered and finally the new "Five Years" box set version, whose provenance remains unknown.
The files are not presented in that order, nor are they identified in any way. This is not a formal test so while I normalized peak levels, these are not all presented at identical levels. Please try to adjust levels for each when listening and don't spectrum analyze and spill the analog/digital beans okay? Just listen for yourself and pick your favorite, or maybe you think they all sound good (or not). Also please comment!
I'd pay particular attention to the güiro and to the flanging on Bowie's voice as well as to the air and space around the instruments. Unfortunately the tracks are limited to 45 seconds to avoid legal issues.
And yes you can say there's something oxymoronic about presenting digital files of what might be digitally sourced LPs, or you could say the entire exercise is moronic, which is fine with me.

(Note: when these files were first posted the file names accidentally gave away their identities. The names have been changed as have the order so "A" before is not "A" now!)
