With Itunes 9, every song I play gets added to the Itunes library, even if I don't want it there. I have Itunes as my default music player on a Windows 7 (64-bit) computer. For example, if in windows explorer, I click on an MP3 file that is not in the Itunes library, Itunes starts up and plays the song (which is fine), but also it adds the song to the itunes library (which I don't want). I don't see any options to change this behavior. Has anyone else noticed this?
