Where can I find iTunes 9 for Tiger (possibly in my language)?
Apple maintains lists of download links of the older versions of their software from the Support section of their website. Sometimes they come up in Google searches, but they are hard to find no matter what. I've grabbed versions of iTunes for Mac OS 10.4 from their site recently, so start digging around their Support section.

UPDATE: Here is the page I was thinking of: http://support.apple.com/downloads/ Just search for the software you're looking for, it shouldn't be too hard to find there
