OK, this is really weird... I reformatted my computer last night and reinstalled everything, except I hadn't copied any of my songs back to my main drive... I DID have my iTunes playlists backed up somewhere, including my smart playlists that I wrote down the settings to (which iTunes could not have understood)... Anywayz, I copied back all my music back to the same place and opened up iTunes, and to my surprise, EVERYTHING was there, including my playlists and smart playlists... THIS IS FREAKY!! I do not understand how this could have happened!! I am 100% sure that I formatted my drive, since I saw the little bar go from 0% to 100% while formatting NTFS (not quick)... Also, I did not tell iTunes to search for music on my drive... And when I plugged in my iPod to be updated, it didn't even ask me if I wanted to make this my main library (which it SHOULD do when you use a "different" computer)... Any ideas how this could have happened?
