From the developer:
iWatchSyncer is a small WPF c# program that will monitor a given location for file/folder addition.
When a mp3 file, or folder containing mp3 files, is added iWatchSyncer will automatically add these to the iTunes music library.
Instead of doing this yourself manually in iTunes!
