Recreating iTunes library from a .itdb file

In iTunes, on your first machine, you will have to go to File|Library|Export Library. This will generate your Library.xml file.
If you take a look in it, you will see for each file all the fields you will find in iTunes (location on HDD, play count, rating, etc...).

Now, on your new machine, after having installed iTunes, you have to go to File|Library|Import Playlists (not obvious at first as I was looking at an Import Library menu but it doesn't exist) and select the xml file you exported on your first machine.

If you try, as I did first, to edit the xml file and overwrite the newly created one, when launching iTunes, it will delete it and create again an empty new one. You have to go through this Export/Import process (which is quite quick).

PS: you may have to edit the xml file anyway before importing, if the paths to the music files changed from your initial machine. For example, I upgraded from WinXP to Win7. As the user folder path changed, I then had to edit the paths c:\users and documents\myuser\My Documents\My music to c:\users\myuser\Music, or something like that, I don't remember exactly.

PPS: Always keep your exported xml file untouched somewhere until you have everything OK on your new machine...

I'm not much of an AppleScripter, so this is modified from some scripts at Doug's AppleScripts website, but it's GPLed, so derivative works are allowed as long as they're also GPLed.

My idea was to make a script that could take the release date, which can't be used in smart playlists, and store it in the last skipped date, which can be used in smart playlists. If you just want to do this for podcasts (not for songs, for which you might actually use the last skipped field), just select your podcasts before running this script.

Once you do that, you can create a smart playlist selected on the "Last skipped" field to get the recently released podcasts.

So here we go:
