Just tried this little app, but it does not find any songs in my library. While I do have about 161 songs on my PowerBook. (The rest is on my other system.) Nothing strange just a default iTunes (7.0.1) install with everything on the places where it should be. All songs in library are from the store though.

Any thoughts on this? I like the look and feel of your app and would like to give it a proper little spin.
