Zeroing COMMENT field?

I have some FLAC files that beets converted to MP3s for me. The original FLAC files had a comment field with info like this.
EAC V1.0 beta 2, Secure Mode, Test & Copy, AccurateRip, FLAC -8

This was saved into a ID3 field that ffprobe reports as:
COMMENT : EAC V1.0 beta 2, Secure Mode, Test & Copy, AccurateRip, FLAC -8

I’m trying to get the Zero plugin to remove these. I added this to my config

zero:
    fields: comments
    comments: [EAC, Exact Audio Copy, LAME, 'ripped by', http, LameXP]
    update_database: true

This is not zeroing the field in question. I tried adding COMMENT to the field list

zero:
    fields: comments COMMENT
    comments: [EAC, Exact Audio Copy, LAME, 'ripped by', http, LameXP]
    COMMENT: [EAC, Exact Audio Copy, LAME, 'ripped by', http, LameXP]
    update_database: true

Now Zero reports that COMMENT is not a field. Which it isn’t in the beets field list.

So what am I doing wrong? How can zero these comments?

Is there a way to do a dry run with scrub? I’m curious what other fields I would lose if I scrub the files instead.

Hi! You shouldn’t need to add COMMENT; only beets field names are relevant here. I’m not really sure what’s going wrong… maybe a good way to start debugging would be to remove the conditions for the comments field and just unconditionally zero it and see if that works? Verbose mode might help too.

Hi guys. I am having the same issue with removing comments. I have hundreds of random comments on tracks that I want to delete. Do I need to list all of these comments to delete them? Thanks in advance.

zero:
fields: comments
comments:
update_database: true

This :point_up_2:does not unconditionally zero

zero:
fields: comments
comments: [EAC, Exact Audio Copy, LAME, ‘ripped by’, http, LameXP, Purchased at Beatport.com]
update_database: true

A lot of my tracks have ‘Purchased at Beatport.com’ even though I add this it still doesn’t remove from the comment on the track.

Hello! Can you please put your config listings into Markdown code blocks? Otherwise, they don’t preserve indentation and other formatting.

You could also try just doing beet modify comments= as a one-off solution.
