ipod woes

Yes, I have a great, wonderful ipod. Only problem is, it malfunctioned about a month ago. You remember, there was a silly post about the geek squad guy...anyway, now that it is working, I discovered that my files on itunes are all screwed up and I am having to re-organize everything. We are talking about something like 12000 songs or something, which I loaded over the course of the last...4 or 5 years...so now on my ipod there is only one album - because I am reorganizing itunes keeps telling me it can't find my music...
Yes, this really is the biggest problem in my life right now. Somehow that is both sad and good...
