Hello,
I've just been playing with library nodes.

I have all of my music videos in two folders called 'Music Videos' and 'Music Concerts' (the second folder contains live performances only)

I've created this node to just show 'Music Concerts':

<node order="50" type="filter">
    <label>133</label>
    <icon>DefaultMusicArtists.png</icon>
    <content>musicvideos</content>
    <group>artists</group>
    <rule field="path" operator="contains">
        <value>nfs://xxx.xxx.x.xx/volume1/Media/Music Concerts/</value>
    </rule>
    <order direction="ascending">path</order>
</node>

I'm trying to group the concerts by Artist.
When I use it, it shows Artists, but when I select an artist it shows content from 'Music Videos' and 'Music Concerts'.
If I remove <group>artists</group> a list of just Music Concerts is displayed.
Is it possible to include an artist grouping just for Music Concerts? Is there an alternative way of achieving this?

I'm using the Aeon MQ8 skin.
