I am looking for a tool to edit tags in MP3s through a script.
The files are episodes of several podcasts where the tags are inconsistent between episode: Sometimes the Album or Genre tag is missing for example. The script will run after new episodes are downloaded to modify the tags.
I have tried id3tool and id3v2 already.
id3v2 does not support free Genre tags, only a numbered list of predefined genres is offered. In this list, there is no genre "Podcast".
id3tool only supports id3v1, where the field lengths are limited. But there is an option to specify free Genre definitions.
Is there a tool that supports all the required functionality? It should compile under Mac OS X 10.6.

Just use Homebrew:

The mutagen Python module comes with a mid3v2 command.
mid3v2 --artist "Sigur Rós" *.mp3
Before you ask: No, mutagen does not support ID3v1, because there is no valid reason to be using it these days.
ID3 Editor
Although the linked website page is oriented towards GUI, it does contain "NEW! Command line editor".
Tagr was recommended; it's free, looks powerful (batch process, cover work, etc.), but not sure it has CLI.
