This request is strongly related to bug #1078

If part of the solution to bug #1078 is to allow the user is able to choose a
filter using the player settings (e.g. by adding MusicMagic settings to the
player plugin menu).  Perhaps the variety and artist style could be chosen by
each player as well.  If the solution to #1078 is the set the filter though the
server settings then this request should be treated as a completely seperate
request.

It makes more sense for the user to define settings per player because, for
example, my kids can better define their mixes in their bedroom, my wife can
choose her settings for the kitchen and I can use my settings in the lounge. 
Given the kids, my wife and I have very different musical tastes this would work
very well in my opinion.
