How good is the rating system?

[lastemp3ror]

I am thinking of getting the 12gb vibez soon. The main thing I am looking for in a mp3 is the rating system. I want to be able to rate songs while I am using the mp3 player. I understand that the vibez now has this feature with the firmware upgrade. How good is it? Is the rating system based on 5 stars? Can I take my ratings and for example ask the player to play only 5 star songs? Or even better, can I ask it to play 5 star songs within a genre or sub-genre?

Thanks
