Spuffy fic; david bowie?!

[missmatronic.livejournal.com]

Hi guys, I am trying to find a Spuffy story that I think is called "Changes", has a David Bowie thing running through it and is fairly long. I think there might be nazi baddies as well?! I also seem to remember that it was written by two people?
I know that whoever wrote Changes wrote another fic that was similar in terms of having a song as a title. Sorry to be so vague, I will be extremely grateful for any help here at all; I have tried so many combinations of words in Google, and was getting some, err, interesting links, but nothing even close to the story I am looking for!

crap, I messed up the html. It should read:

Thank you! That has made my befuddled brain much happier!

Except, IIRC, the Nazi baddies are in The Heart's Filthy Lesson, which is the first fic in the series. It goes:

Heart's Filthy Lesson - Nazi Demons
Serious Moonlight - Time Travel Mummies
Changes - Rockstar Vengeance
Buffy Summers and the Spiders From Mars - Xander's KITT

One of the most excellent series out there.
