My Library has ten more songs than my iPod. How can I find out which songs are not syncing?

I recently had to purchase a new hard drive. Because the size of my music collection exceeds 140 GB, I stored all of my music on a separate external hard drive. When I exported everything back into my new iTunes library, I found that I had about 200 more songs than I had in the previous library. After deleting most of those extraneous songs, I was able to get my library close to where it was before. However, after syncing to my iPod Classic, I noticed that only 34,853 of the 34,863 loaded. How can I figure out which of those ten songs in my library did not sync to my iPod?
