More Zune Gotchas [Autoplaylists]
When setting up your Zune Software, one of the settings under Collection is for 'Zune Folders', where it will presumably store data when you rip CDs or download albums from the Marketplace. This is also where it will save any playlists you've created inside of the software.
Now obviously when you uninstall the software, it will keep this directory intact since it could potentially contain some of your music files. What it doesn't tell you is that it will automatically import any data it finds in your playlists! After running through the steps of my previous posts, it was still finding some of the albums from directories I was no longer including in monitoring and it was driving me crazy. I had kept my playlists because I had a decent number and didn't want to recreate them. Joke's on me because it just took all the tracks from those playlists and reimported every single one, including ones from when I was still using the 4.2 software!
So if you had any autoplaylists created, ensure you delete those (and really probably anything else inside that directory, to be safe) or else it will still import anything it finds in there.
