I'm using this as well on Windows 7.
Could you include a function to set the rating of each song with one of the 4 buttons below the display?
e.g. A song is not rated, I press the left button once, now it has 1 star, then 2,3,4,5 and then 0 again.
Rating like 200 low-quality songs a week to see which need to be bought is a hell of a task.
I could include the feature on my own so you don't have the work.
Hook me up via PM if needed
Until now I assigned 6 of the G-Keys for Rating from 0 stars to 5, but I had to bring Media Center to front each time which bothers me while I work.
