Shuffle seems not so random?

they Use an Algorithm but I am not sure what one. HOWEVER there are other factors, If you have rated songs on the fuze, in Windows media (or another software) , or in explorer the fuze can see that info as it is often saved as part if of the ID3Tag for the file. I say this not knowing if it actually effects anything but I have noticed that mine favors songs that are unrated in the fuze but rated highly elsewhere.
