iProtal is a free, opensource automatic tool for adjusting Metal and Progressive Rock / Metal genre of iTunes songs. It scans an iTunes Library of songs, or the currently highlighted / selected songs in iTunes, and automatically fetches the genre for all the artists.

At the end of this page you can find some screenshots

Currently, it fetches the genre from:

At the current state the program only works in Terminal mode, so everything is displayed as scary text. The author is not planning to write a graphical user interface now, but welcomes anybody who offers to write one.

  1. Install py-appscript First, install py-appscript as it is required. From the terminal, run
sudo easy_install appscript

Other ways to install it are available on the official website

  1. Run the program’s main.py. If you are not confident with the terminal, an easy way is to open the “Terminal” application of Mac OS X, type “python “ without the double quotes (followed by a space, as you see), drag the file src/main.py in the terminal and hit enter.

Run iProtal 1

Run iProtal 2

HOW DOES IT WORK? For any selected iTunes song (or the whole iTunes Library), the program fetches the genre from the fetchers in the order listed above. The possible cases are:

  1. No genre is found The tracks for which no genre could be found are stored in memory and displayed before exiting the program.

iProtal No Genre Found

  1. A Genre is found The tracks genre is automatically updated without user interaction.

iProtal update iTunes genre

  1. More genres are found This happens with Enciclopaedia Metallum when more artists are found under the same name. The program delays the processing of the related songs and continues with the next group. Before exiting, iProtal asks the user which genre is more suitable for the tracks.

iProtal Multiple Genres found

WHEN DOES IT NOT WORK? The program won’t work:

  1. In case of bugs Please drop a mail to d AT danielgraziotin DOT it, describing what happened, including the program output. The author will fix the bugs

  2. The Artist name is not the same as the one stored in the remote fetchers Please try to use official names when naming Artists in iTunes. “F4tesWarn1ng” is not the same as “Fates Warning”. The program does not care about upper cases.

MORE FETCHERS? Send a mail to d AT danielgraziotin DOT it and suggest a new source for getting genres. The author will be happy to add it in his very scarce free time.
