My audio files are pre-tagged using Picard.
When importing these files, does beets take into consideration the pre-existing musicbrainz metadata?
Basically I find musicbrainz very useful for managing the initial matching in a gui oriented way, but once the relationship is established i prefer the batch oriented beets way.

Yes, beets uses the existing metadata, including IDs in the files' tags.

You can also use -A to use the existing metadata as-is every time, without looking it up again.

Good. What made me wonder is that the process for importing already picard-tagged folders with multiple CD (cd1, cd2 or disc1, disc2) seem way more complicated than I would expect. Lots of questions gets asked, while since the ID are already there I would expect no questions..

Beets still needs a way to decide which songs are part of each album (described in the autotagging guide).

If something specific seems wrong, could you provide an example (along with what you expected to happen)?

this is it. As each file is tagged with the musicbrainz release id/release group id, why does beets need to decide anything?

Did you mean to paste example output here?

Beets' importer balances the signal from the ID with other signals, like the track titles. If they don't line up perfectly, it asks you questions.

OK, import log following..

@zuzzurro

Before pasting the log, let me ask one more question.
In a multi cd case, Picard (Musicbrains?) names the tracks as 1-1, 1-2...1.10, 2-1,2-2 while beets seems to prefer 1,2,...,10,11,12...
while in the single cd case it just goes 1,2,...10
Is there a way to emulate the picard behavior in beets?

Please search the docs for per_disc_numbering.

will do right away

@zuzzurro

ok, seen that:
If you enable per_disc_numbering, you will likely want to change your Path Format Configuration also to include $disc before $track to make filenames sort correctly in album directories. For example, you might want to use a path format like this:
can i add the the disc number only in the multi-cd case?

The FAQ will help with that.

And here is the log. With per_disc_numbering it's tidier, still my guess is that the questions do not come from a real difference but from different defaults from picard.

it seems beets is complaing about "(tracks)", because it manages the tracks in multiple cds in a different way. Is that correct?

@sampsyo

Yep. Looks like beets is tagging this automatically, without user intervention, except for the duplicate detector (which is not related to metadata matches). Is there still a problem?

That's just indicating that the tracks' tags don't have a disc number, but beets wants to add one.

@zuzzurro

I think we are mostly fine.
Apart from checking the FAQ for adapting the naming to making it more similar to the Picard way, there's one last small issue.
As you can see above there are two copies of the same disc that are tagged by picard in the exact same way (I retagged them 1 minute ago) still beets complains about the tag of

Poker Face (#4) -> Poker Face (#2-4) (id)

How can that be?

@sampsyo

sampsyo commented Mar 23, 2016

That's indicating that there's an ID mismatch. Maybe you can dig in a little further and investigate why (which IDs didn't match).

Gees, there it is. A different recording ID..

Amazing. In Picard the two files are exactly the same. Looks like it botches writing the tag in the file..

OK, got the multidisc configuration right. One last thing, is there a way for disc numbers to go from 1 to 9 instead of 01 to 09?

@sampsyo

sampsyo commented Mar 23, 2016

One hacky way is to use the inline plugin to define a $mydisc field that is just an alias for disc.

@zuzzurro
Copy link

Or adapt this example from the inline plugin page :

item_fields:
    initial: albumartist[0].upper() + u'.'
    disc_and_track: u'%01i.%02i' % (disc, track) if
                    disctotal > 1 else u'%01i' % (track)

Right?

I have been meaning for more than a year to adopt beets for managing my music library. Now that I started really doing it, it's performing the way I hoped. Thanks a real lot.
