Currently I am mapping out my entire music library.

First I label my track correctly:

Year_Artist_Track Name

Secondly I sort these tracks into their correct genre / sub genre folder taking reference from the following websites:

When a genre folder becomes too crowded I will divide this genre into two sub genres.

This work is very important to me as I research ever more deeply into the theory, sociology etc. of sound.
My library becomes increasingly my musical dictionary, catalogue of audible references and links to cultures.
