From time to time I get questions from customers struggling to set up iSyncr combined with PlayerPro.  These two apps work great together once setup, and we certainly do not want setup to be a hurdle, so let's walk through these steps right quick.

1.)  Download and install PlayerPro or PlayerPro Trial
2.)  Open PlayerPro
3.)  Go Menu->Settings

4.)  Choose "Music Library"

5.)  Choose "Rating System"

6.)  Choose iSyncr

7.)  Choose "Scrobbling"

8.)  Choose "Simple"

Now you are all set up!  You should see your ratings in the app and (if you configure one) on the lock screen!
