Get genres from discogs

JS (JXA) script that fetches genres for iTunes tracks by scraping discogs.com. Runs on recent versions of OS X.

Usage

• In iTunes, select the tracks you wish to tag
• Run the .scpt file from Script Editor or use an applet .app exported from Script Editor
• Place the exported .app in ~/Library/iTunes/Scripts to run it from iTunes' menu bar.

A log will be created on your desktop with the results.

About

This is still 'beta' and refinements need to be made regarding accuracy, handling of compilations, etc... It is written in JXA, essentially Javascript for Mac apps - made to function as an alternative to AppleScript.
For info on this check out:

• Apple's Javascript for Automation Notes
• dtinths's JXA Cookbook

To do

• Handle compilations better. Multiple artists in an album or ✔︎Compilation must exclude artist from search, or use album artist.

• If album artist fails, try with artist tag

• Check for genres and styles listed on an album's /release pages

• Diffquotient function must be improved.
  ex: The Bug - Can't Take This No More
  does not match: Bug, The - Can't Take This No More / Rise Up

• Support concurrent tagging of two separate albums with the same name

• Create iTunes playlists for each found genre

• Option to add other albums by same artist in genre-specific playlist

• Make script self-check for updates via compluter.com

• Tagging fallback to wikipedia, last.fm, bandcamp, musicbrainz etc.

• Get record label name feature
