guys, I don't think HIS st epreo is 1:43 length. If you look at his listening history and click st epreo is takes you to the common page for that song which for some reason is that length. I found a patch of his history where he listened to much of the album and st epreo is logged at 14:05, redfall is logged at 14:09... 4 mins later, which is what my st epreo is!
here's the page I'm talking about: http://www.lastfm.de/user/DavBrav/tracks?page=5
there is also another occurrence of st epreo followed by redfall here (also 4 mins): http://www.lastfm.de/user/DavBrav/tracks?page=10
mystery solved??? I think so...
