There are rule type nodes, where you use same syntax as for smart playlist rules, and folder type which are more like the default nodes. Here is an example of a folder type music node that will work in Krypton onwards.

Let's presume that you are intereted in music producers, and have tagged your music with the producer e.g. PRODUCER in FLAC or TIPL name (Producer) in ID3. This node will list those producers.

Code:

<?xml version='1.0' encoding='UTF-8'?>
<node order="6" type="folder">
<label>Producers</label>
<icon>DefaultMusicArtists.png</icon>
<path>musicdb://artists/?role=Producer&amp;albumartistsonly=false</path>
</node>

Can do the same with any artist role e.g. composer, conductor, DJMixer etc. The standard roles are: Composer, Conductor, Orchestra, Lyricist, Remixer, Arranger, Engineer, Producer, DJMixer, Mixer. But use of the PERFORMER or TMCL and TIPL tags can create others e.g. Soloist, Drummer etc. that can be used in juts the same way.

Note the use of "albumartistsonly" to override the system albumartistsonly setting in case it is enabled, and always show all producers. If this was albumartistsonly=true it would only show those producers that were also listed as an album artist. Limiting to a role and album artist makes sense when you want to list say just composers for classical music albums rather than the composer of every song.
