MusicBrainz Server update, 2020-10-19

Today’s MusicBrainz Server brings a new data report, a continued conversion to React, some bugfixes and small improvements, but also tests refactoring.

Meanwhile, the search server has been updated twice in a row to fix bugs in JSON output mostly with MB Solr 3.2 (release notes) and MB Solr 3.3 (release notes), including the MusicBrainz API breaking change announced last month.

A new release of MusicBrainz Docker is also available that matches this update of MusicBrainz Server. See the release notes for update instructions.

Thanks to amCap1712 for fixing bugs in MB Solr, and to loujine for contributing code with yet a new data report. Thanks to Avamander, bonchiver_, chaban, draconx, eloise_freya, GTF1982, hawke, hibiscuskazeneko, jesus2099, jrv, kellnerd, Kid Devine, Psychoadept, selflessself, and wcw1966 for having reported bugs and suggested improvements.

Helping out

The easiest way to help us getting a great Picard 2.5 release is using and testing this release candidate. Please report bugs on the Picard issue tracker and provide feedback in the community forums.

Please also help translate Picard. There have been many changes to the user interface and existing translations need to be updated for the final 2.4 release. Translating is easy and can be done online: Head over to MusicBrainz’s translation page on Transifex and click on “Help Translate MusicBrainz”.
Once you have registered an account on Transifex you can start translating. For Picard the primary resource to translate is “picard“, but there is also the “picard_appstream” resource which is used for providing descriptions for various Linux software-center applications.

If you are a software developer you are very welcomed to provide fixes and features. Picard is free software and the source code is available on GitHub. See Developing on the Picard website to get started.

MetaBrainz Projects in the news

During the summit this past weekend we talked about posting more updates to our blog. In the spirit of that, I wanted to share two articles where MusicBrainz and AcousticBrainz were recently mentioned in the news: In July the BBC wrote an article covering research from UC Irvine in California:

They found a significant downturn in the positivity of pop songs. Where 1985 saw upbeat tracks like Wham’s Freedom, 2015 favoured more sombre music by Sam Smith and Adele.
The UC Irvine research team analyzed the publicly available data from AcousticBrainz to arrive at this and several other conclusions.

This wasn’t the first time that our project was used to analyze music trends over time and we’re proud that researchers can carry out this kind of work on our public data. In October Insead Knowledge wrote about the gender gap in the music industry:

We also used song credit information from crowdsourced database MusicBrainz to determine how many women and men worked on the writing, production and performance of each song. . . . At first glance, our overall results appear quite simple. In line with past research on creativity, we find no baseline relationship between the novelty of the songs in our sample and the gender identity of the artists involved. Men and women appear to be equally capable in terms of creativity. But when we controlled for genre and, importantly, the gender composition of artists’ genres, the picture changed. Our methods were guided by an awareness that women in music work in a different context than men do: By a kind of gender-slanted gravitational pull, the music industry drives women into certain genres (e.g. pop) and collaborative networks.
We’ve long known about gender imbalances in the music industry and while we’re happy that people are using our data to demonstrate this, we’re dismayed at most of the findings in this article. What is more concerning is that we have a general impression that our community has a slight bias towards adding more information about music created by women, which means that the overall situation may actually be worse than what one can deduce from our data!

As a reminder, all data in MusicBrainz is contributed by members of the community. If you see any situations where women or minorities are being mis- or underrepresented, we encourage you to add this content to MusicBrainz. And if you get stuck, don’t hesitate to ask for help on the forums.

MusicBrainz Server update, 2020-10-05

As we just returned from the virtual MusicBrainz Summit 20, here comes a mostly maintenance release that fixes a bunch of bugs (among which many are about localization) and provides a few handy improvements. It even features a new report showing releases having the same barcode but currently in different release groups, so if you feel like it, do try and help us look into those!

A new release of MusicBrainz Docker is also available that matches this update of MusicBrainz Server. See the release notes for update instructions.

Special thanks to the DistriNet Research Group for making and responsibly sharing a very detailed audit of our OAuth service that has been very helpful with releasing major security improvements in the previous server update!

Thanks to chaban, fabe56, hibiscuskazeneko, humhumxx, jesus2099, lotheric, mfmeulenbelt, nikki, otringal, psychoadept, and wcw1966 for having reported bugs and suggested improvements. Thanks to dimpole, listmycds, mfmeulenbelt, peter9811 for updating the translations. And thanks to all others who tested the beta version!
