Managing a big music library can take a lot of work and investment. Keeping tags, playlists, ratings and artwork up to date can be a real chore. Luckily there is a tool, the iTunes Store File Validator, that could help by automatically adding ratings to your iTunes music.
The iTunes Store File Validator automatically applies a rating to your files based on how often they are played or skipped, which can be handy if you a large library. However, it does have a few drawbacks e.g. if you skip a song because you’re not in the right mood to listen to it, rather than it being no good.
