Comparing iTunes library with music folder

[kylera]

I wonder if there is an app/script/plugin that compares an iTunes library with the folder(s) the library is tied to, and shows songs that are not in the library, but in the folder(s). For example, I have A, B, and C in the library, but my music folder has A, B, C and D, and the app/script/plugin shows D.

Look for "Music folder files not added" on Doug's Scripts.
