I have about 250 cds in my Itunes account and want to know what im doing wrong that has the shuffle mode only play the same songs.I play my itunes account at work and in the course of a day some songs are played more than once,some have never been played and some cds always skipped while others are always played.Cant figure out how this shuffle mode works if it never touches on some cds or songs and always plays others.Any suggestions greatly appreciated.
