I own all the text Murphy games and I have downloaded the soundtracks to HAMMER and TPD but they are organized alphabetically as opposed to a real soundtrack album. Has anyone worked out what order the tracks go in? Thanks.

Don't think they were released as a true soundtrack-cd or album, at least not TPD.
All places I've seen them they are alphabetically, but you can organize them after location or chapter if you want some sort of chronological order.
