Selecting a set of tracks

[Pastim]

I'm struggling a little with selecting sets of tracks. I suspect I'm being a bit slow, so please bear with me.

I have a list of items on display. If these are Albums, I can select one and send all of it to be played with one click.

If these are, say, Artists, I can't do the same. Is this intentional? It would be useful to be able to play a set of tracks belonging to any tag at any level (except the very top level). I am aware of the 'Group' concept, but I haven't implemented this, partly because it would be a heck of a lot of work, and partly because it is, as far as I know, unique to minimserver. I do have 'Work' tags, but they suffer from the same problem as Artists. It seems I have probably failed to comprehend something fundamental, but it seems counter-intuitive to me.

I am not entirely sure whether this is a feature of minimserver, or of my control points. I have been using foobar2000, and a new one currently being developed called upplay.
