year and genre treated as album-level tags in compilations

[prstoner]

Hi,
all of my compilations (comp=True) have their year, genre and albumartist_sort tags treated as album-level tag. In contrast, all the other albums (Comps=False or empty) seems to have those tags managed as track level tag, allowing for the same album different values for years.

This is very problematic for compilations, given the fact that is very common for them to have tracks originally released in different years, or belonging to different genres (i.e. live recordings of music festival).

The huge issue is that beets stores in the db only a single value - usually from the first track - and when i run write that value overwrites the individual track tags, resulting in wrong metadata.

Is this the intended behavior ?

I built the library with:
beet import -A ~/my/music/folder && beet update

my config is

import:
    copy: no
    write: no
    incremental: yes
ui:
    color: yes
pluginpath: ~/beets/myplugins
plugins: edit info
max_filename_length: 16
paths:
    default: %left{$albumartist,16}/$album%aunique{}/$track.%left{$title,5}...%right{$title,5}
    singleton: non.album/$artist/$title
    comp: compilations/$album%aunique{}/$track.$title
asciify_paths: yes
