I think I started with MORT and have also read Good Omens. I have Thief of Time and am currently reading Making Money. I've missed so many in the middle.

Most of the Death and Susan (Goth Marry Poppins) books need to be read in order to understand Susan's development. I'd recommend reading them thus:
- Mort (To understand events in Soul Music)
- Soul Music (Susan's introduction and why she reacts so negatively to Death showing up in later books)
- Hogfather (Susan tries to reject what and who she is and fails.)
- Thief of Time (Susan accepts what she is, but on her on terms. She seems much happier for it... well, as happy as SHE can be anyway.)
Soul Music can probably be read as a stand alone too. Looking back, it's almost hilarious how alike the Musician's Guild and the RIAA are. The Wizards turning into pirates is also funny, when they make the box that can record music (So you'd no longer NEED Musicians).
