Ah well this, or something similar, is what I have been craving ever since I bought my B2, four years or so, ago.
Ray has defined the requirements perfectly and, as he says, we do already have the first two, i.e., random for the entire collection and random within a playlist.
What is missing is random by artist and random by CD (or whatever means you have used to download your music).
We are told these features are on the wishlist, and yes, there's a workaround (there's always a workaround), but really, who wants to keep creating playlist after playlist, or adding and removing artists or albums to and from a playlist?
I've mentioned before that, obviously, there is an algorithm of some kind that works for random as it is now and how hard would it be to make that work for the missing features described?
Then we could move on to more esoteric options such as play/random by year of release, artists/albums/songs, starting with a certain letter, recently added etc. You know, like every other music-playing device.
But, one step at a time.
Happy Easter,
Les
