what is the [1234] id attached to the end of my folder names?

[upwindchange]

Hi team, I have multiple folders being double imported:

'西木野真姫(CV.Pile)':
'soldier game'  'soldier game [2212]'

'西木野真姫(CV.Pile),園田海未(CV.三森すずこ),絢瀬絵里(CV.南條愛乃)':
'soldier game'  'soldier game [2212]'

'西野 カナ':
'Just LOVE'  'Just LOVE [2485]'

西野カナ:
 Always  'Best Friend'   I  'Love Collection 2 〜mint〜'  'Love Collection 2 〜mint〜 [2763]'  'Secret Collection ～RED～'

Could you help me understand what is in the square brackets in each folder names? I want to understand what they are first then I can figure out how to get rid of them.

Thank you for your help.

it's probably the id of the album in the beets library. since you have doubles the disambiguation mechanism does that

I believe this comes from %aunique{} in the default config. you can set different path configs without it.

paths:
    default: $albumartist/$album%aunique{}/$track $title
    singleton: Non-Album/$artist/$title
    comp: Compilations/$album%aunique{}/$track $title

I think you can show the beet album id with beet ls -f where -f or --format sets the result format. Confirm in the docs and the beets help option. (beet -h)
