Tony,
Thanks for a great post. I think that I understand how it works.
However, there is a very simple UI design to give me all of the functionality that I want, without searching, relying on the order of your playlists, having to use the remote *at all*.
Use the volume button, to bring up a menu with three options:
1) Artist - gives us all of the songs on the empeg with the same artist
2) Album - as above, but just for the album - although I agree that this is also done via the '0' button
3) Genre - all songs on the empeg with the same genre as the current song.
I agree that you can do most of these things via the methods that you mention, but I think that this will be a lot more intuative with the above solution. I also appreciate that this isn't possible currently, and that I'll have to try the solutions as recommended.
I'm definitely open for ideas/comments.
Cheers,
Paul.
PS Please don't take this discussion the wrong way - I know that I have a habit of sounding agressive in just text....
