Nice tool if you know how it works. Try out with just a few songs to see how the slider settings affect the rating. NOT recommended if you do have most of your library rated already, since the effects may kill your rating system.
Overall a useful addition, not replacement for manual rating.

Ok, new version works for me now. Really great use for that underused star-system!

Works great for me. I was never really sure how to use the ratings system efficiently, but this app solves that problem for me!

Too sad, it doesn't work for me. Gives me two Applescript-errors on start.
