New "Grouping" WPS tag option--explanation of what it does/how to best use?

(1/2) > >>

Mikerman:
Could someone explain the new Grouping WPS tag option and the benefit it provides/how one might want to best use it?  I somewhat understand the concept and its value for classical music collections but am just trying to envision it in operation, including for other than classical music.  Thanks--

Perhaps it could work well with a series of albums, like a numbered Various Artists collection.

dip:
Most important it is for classical music (that's what e.g. iTunes use it). If you have a classical album comprising e.g. two symphonies of Beethoven you can use the album tag for the album title (e.g. ALBUM=Beethoven - Symphonies No. 5 & 7), the grouping tag for the work title (e.g. GROUPING=Symphony No. 5) and the title tag for the movement title (e.g. TITLE=Allegro non brio).

Then you can include in tagnavi_custom.conf an entry for browsing by classical works.
If somebody is interested, here is a copy of my present tagnavi_custom.conf file which usese the grouping tag (and which is still in development):

#! rockbox/tagbrowser/2.0

What is the WPS command used & exactly which fields does it recognise?

dip:
The following tags are supported:
- id3v2.2 (TT1), id3v2.3 and id3v2.4 (TIT1),
- mp4 (cgrp)
- vorbis comments (GROUPING as used by MusicBrainz, CONTENTGROUP as used by MP3Tag and CONTENT GROUP as used by foobar2000).

In WPS you can use %iG (for the present track) and %IG (for the next track).

As tagnavi.conf tags "grouping" and "contentgroup" are supported but not "content group" due to the space in the middle.
