is there a way to use a random playlist where songs are pulled from the entire library? my gf just tried to do it and once I looked, I found it was taking the first song in the usb library and just going down the list sequentially. I assumed it was going to select song 5,18,67,3,74, etc. it was just going 1,2,3,4. I selected the dice and the consume mode but it was not making a difference. am I selecting the correct option/method or is there another/better way to play the library randomly?
