MacOS – Circuit simulator tool for OS X

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]...

A lot of small and big developers use Distimo Monitor, most probably because they like the feature set, number of supported stores and ad networks and also because they trust the data privacy and security. Just give it a try, for questions you can always use the contact form.
