Is there a good command-line ID3 tool for OS X? Anyone know of a command-line* ID3 tool, with support for ID3v2, that you can get working on Mac OS X with reasonable effort? It should support both reading and writing tags.

(* I want to be able to call it e.g. from some Python scripts, so a GUI tool won't do.)

The id3tool utility is otherwise good, but doesn't support ID3v2 (and thus doesn't play that well with iTunes). I had to compile it from source, but that was pretty straightforward on a Mac with Xcode &amp; developer tools (including, notably, a C compiler). Anyway, I'd especially like something with similar command-line options as id3tool. Here's an example of tagging one file:

id3tool -t "Song Title" -r Artist -a "Album Name" -c 2 track-02.mp3
If you have Homebrew installed (highly recommended), you can just do:

brew install id3lib


This installs several id3 command-line tools, including id3tag, id3convert, id3cp and id3info.  No need for python or perl scripting; just use regular shell commands.

Usage: id3tag [OPTIONS]... [FILES]...
