Audacious displays "(0)" when the tagged genre of an mp3 file is "Blues"

[mikepur]

Describe the bug
Audacious displays "(0)" when the tagged genre of an mp3 file is "Blues"

Steps to reproduce
Tag any mp3 files with the genre "Blues" using whatever method you prefer (Thunar, eyeD3, EasyTAG), Audacious always displays "(0)" instead of "Blues" (without the quotes). This looks like a typical array pointer problem.

Sample output of eyeD3 on an mp3 file tagged with genre Blues

eyeD3 "1-01 John Lee Hooker - I'm In The Mood.mp3"

Does the MP3 file in question have an ID3v1 tag?

[mikepur]

No, looking at the output of the eyeD3 command in the initial bug report the tag is ID3 v2.4

[mikepur]

This is a very long standing bug and has existed since I've been using Audacious, which is at least 10 years. I always just assumed that it was so obvious that many people would have reported it already. I guess not many people use the genre tag to help create playlists or to sort their collections.

For issues like this, sample files are always essential. Please upload a small sample file (preferable without copyright).

Can you reproduce this with MP3 files from https://samplelib.com/sample-mp3.html?
I used Thunar to edit the genre tag and it is displayed as expected in Audacious.

What happens with other genres?

Why does eyeD3 output "Blues (id 0)" instead of "Blues"?

[mikepur]

I use easyTAG most of the time to tag the genre of mp3 files, mostly because I can tag multiple files at the same time. I check the tag using Thunar. Downloading the sample file I used easyTAG to set the Genre to Blues, Thunar reports that the Genre is Blues. Audacious reports the Genre as (0). If I then use Thunar to set the genre and save the results Audacious correctly displays the Genre as Blues. So Thunar seems to be able to decode the correct genre from easyTAG but audacious needs something extra that Thunar either adds or corrects to the metadata. Audacious does not seem to have a problem with many other genre tags that easyTAG can assign. Rock, Punk, Classical, Comedy, and Pop et. al. all seem to work fine.

Attached are copies of the sample files tagged with easyTAG and Thunar so perhaps you can analyze the difference.

eyeD3 maps each genre to a unique ID - Blues is (id 0), Rock is (id 17), etc. In ID3v1 there was a list of IDs that mapped to Genre see https://en.wikipedia.org/wiki/List_of_ID3v1_genres . I'm not sure how or if this changed with later versions of ID3vxxx, but for a Genre like "Power Pop" which is not in the ID list defined above, eyeD3 reports genre: Power Pop (id None). Thunar does display "Power Pop" and audacious displays nothing, the field is blank. It does seem overly restrictive to limit Genre to one of 255 as Genre would seem to be something that would evolve as music evolves, as new genres are always being created. Seem to me that genre should be user user defined, and easyTAG allows user defined Genres, and Thunar seems to be able to read them. Audacious does not.

[mschwendt]

Yeah, it's reproducible with EasyTAG 2.4.3 and any MP3 file here:
Remove Tags, add Genre "Blues", then Audacious displays Genre "(0)".

Thanks for the further details, I could understand now what's going on here. See the pull request #1647.
