Remove default iTunes genres

Customising iTunes Music Type:

The "genre" drop-down list that iTunes offers (under "get info") has too many choices; some are completely unwanted. Here is a simple way to make that choice more suitable for your specific taste.

• Close iTunes v12 program
• Using NotePad++, edit both files:
• C:\Program Files (x86)\iTunes\iTunes.Resources\en_GB.lproj\Localizable.strings
• C:\Program Files (x86)\iTunes\iTunes.Resources\en.lproj\Localizable.strings
• Check around line nr 13'995 and look out for the section labelled:
/* ===== Genres ===== */
...
/* ===== HTTP Utilities Strings ===== */
• Delete undesired lines (genres)
• Save "Localizable.strings" files
• Restart iTunes program

Note:

• To remove exclamation points from your iTunes library, hold the Shift key while launching iTunes to bring up the library selection dialog. Select “Choose Library” then click on file “C:\Users\d022519\Music\iTunes\iTunes Library.itl”.
