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

[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.

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):

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.

[safetydan]

Actually I took contentgroup out as there didn't seem to be much point in supporting both in tagnavi.

Thanks for this elaboration. :-) Now, are 'content groups' larger or smaller than albums? Discs? I'm just trying to figure out what other contexts one would use this tag besides a symphony.

[bascule]

As far as I can see, the GROUPING tag is a super-grouping, falling somwhere between album and genre in scope.

You could perhaps use it to divide your favourite artist's long and distinguished career output into smaller sections such as:
Pink Floyd - Syd Barret era, Roger Waters era, post-Waters era
Elvis - Sun studios, RCA, Hollywood years, Vegas years

[Mikerman]

Or perhaps for sub-genres:  Country, Depressing; Country, Uplifting.

Assuming that any text-string can be used, I guess you could use this field, despite it's name, for anything desired.
