i'd like to have a tag that defines a multiple-value,
e.g.
song1:MYTAG ="classic;fast;high-pitch;funny"
song2:MYTAG ="folk;sad;fast"
song3:MYTAG ="pyschadelic;folk"

and then to be able to group by these tags (in the library, or as a dynamic playlist, or anything that works)

e.g. (by the above example) :
|
+- fast (2)
+- folk (2)
+- classic (1)
+- funny (1)
+- sad (1)
...

so that each song can have multiple ways to be grouped by. The groups can overlap.

How do I achieve that?

EDIT1:
I can partially achieve it now with the following steps:

for each song:
add a tag (e.g. MYTAG) to a song,
set that tag multiple-values with a separator (e.g. "folk;sad;fast")
right-click that tag,
choose "split values..."
save changes.

I noticed that even though the comment in the edit window says "use ; character to separate multiple values",
the media library still treats it as a single value, unless i choose "split values..." like i wrote above. (Is this a bug? how can it split values automatically?)


In foobar settings:
preferences -> media library > album list > (add new/edit)
add a view with that tag (e.g. "%<mytag>%")
save preferences.

i learned that %<mytag>% treats the field contents as a multivalue field
and %mytag% treats the field as a single-value field.

in the bottom of the media library tree, select the new view.

Now library shows me
groups by tags.

I can combine songs from several groups with CTRL key - OR() operator.
but how can I select groups that contain only selected tags? i.e. AND() operator

by "OR" operator i mean:
foobar selects each song that belongs to EITHER of the groups. e.g. songs that are defined as "rock" or songs that are defined as "pop".

by "AND" i mean
foobar selects each song only if it belongs to ALL of the selected groups. e.g. songs that are defined as BOTH "rock" AND "pop" simultaneously.

Complete re-Edit My Question

a) how to group multivalue tags in the library by AND() operator (see below)
b) how to edit multivalue faster and easier?
c) is there a bug in editing multibalues? (see end of this post)

To group the library by multivalue tags, I edit foobar settings:
1) preferences -> media library > album list > (add new/edit)
2) add a view with that tag (e.g. "%<mytag>%")
3) save preferences.

i learned that %<mytag>% treats the field contents as a multivalue field
and %mytag% treats the field as a single-value field.

in the bottom of the media library tree, select the new view.

Now library shows me
groups by tags.

background information:
how to group the media library by multivalue tag fields

i'd like to have a tag that defines a multiple-value, e.g.

I use the following steps:

For each song:
1) add a tag (e.g. MYTAG) to a song,
2) set that tag multiple-values with a separator (e.g. "folk;sad;fast")
3) right-click that tag,
4) choose "split values..."
5) confirm using ";" as a separator,
6) save changes.

I noticed that even though the comment in the edit window says "use ; character to separate multiple values",
the media library still treats it as a single value, unless i choose "split values..." like i wrote above.

AND

QUOTE
$if($and($strstr(%mytag%,rock),$strstr(%mytag%,pop)),display this)

$if($and($strstr(%mytag%,rock),$strstr(%mytag%,pop)),display this,otherwise display this)

OR

QUOTE
$if($or($strstr(%mytag%,rock),$strstr(%mytag%,pop)),display this)

$if($or($strstr(%mytag%,rock),$strstr(%mytag%,pop)),display this,otherwise display this)

Be aware that what you stipulate $strstr() to look for is case-sensitive.

Consult the Title Formatting Reference for other options.

Add MYTAG to the list at Preferences > Advanced > Display > Properties dialog > Multivalue fields.
