Here are two examples showing how to script iTunes for Windows with Python. See below under "Discussion" for additional comments and explainations.

Since most of the script for iTunes you can find of the web are written in AppleScript, I was wondering how I could script iTunes for Windows. Then I discovered that iTunes for Windows had a COM API. Python having a very nice interface to COM (thanks to the win32com module), that make it very easy to script iTunes with Python.
There is nothing very sophisticated here, but there may be some others "Python and iTunes users" that are not aware of this possibility (as I was just a month ago). So I thought I would write a small recipe (my first so far) for that. Additionaly, It makes for a simple introduction to COM programming with python.
You can download a documentation of the iTunes COM interface at the following address: http://developer.apple.com/sdk/itunescomsdk.html The doc is bundled with some C header, but don't worry, you do not need them. You only need the win32com module (which is already bundled with ActivePython)
The second one is a script I used to automatically add lyrics to the songs in my library. This script is of course not very useful in itself without the getLyrics function that provide the lyrics text. But it is a good example of how to create playlist and modify the fields of a song. I happened to have a small database of lyrics, so that was useful for me. If you are really interested in obtaining lyrics for your songs, look for lyrics website that provide a web API.
Hey, this is pretty cool! Would you consider helping out on this project: http://code.google.com/p/autoqueue/ to port the crossplayer autoqueue plugin to iTunes for windows? Someone is already working on a iTunes for mac version, so maybe you could collaborate. I'd really like to have at least one windows based player supported, but since I'm not a windows user, I won't be able to do it/test it. I *will however help you port it and explain what needs to be done, and it shouldn't be too much work: It's basically just extending a base class and implementing a few player specific methods.
[*] Autoqueue is a crossplayer plugin that gets similar tracks to the ones you play from last.fm and puts them in the queue. It is smart enough not to play the same artists/songs for a configurable time, and has some other options. It works pretty well in creating a consistent yet not wholly predictable listening experience if you have a large and diverse library.
I suppose it's similar to the new genius feature, but more configurable, and from what I hear, for now the last.fm similarity searches are a lot better.
