thank you and some questions...

Really thanks for all the comment! And I think I understand. For each server and controller combination, there may be some workaround for some operation, and there is always limitation. For example, if there is no duplicated listing under a Artist branch, in PlugPlayer, let's say I have 26 artists, names from A to Z. In PlugPlayer, I can select "Select" at the Artist level, and select artist A, D, M, and S, to listen to all song from these 4 artists, in 1 go. But in your example, I need to do multiple selection under each of the 4 artists for this operation. The discussion is endless! There is always pro and con in this "dumb" system...

While a better server side browsing is always welcome, my current ideal setup is a "dumb" server with a full "search" support, then a really smart controller which can do most of the work, and let user to customize to whatever each preference...
