When I first got my 5 disc changer, I used the random play function a few times, loading up, say, all of my Mobley discs. But then I started to realize that the random play wasn't really random-some discs were ignored for way, way too long. I mean, I know that if you are flipping a coin, you could get ten "heads" in a row but still have a fair coin being used, and that the odds of the next "head" is still 50/50. But when your "random play" function keeps selecting tunes from discs 1, 3 and 5 for thirty minutes, I think its fair to assume that the function isn't fully functional.
So, being a bit annoyed I stopped using it altogether.
Never got that much out of it anyway.
