Then each level 2 can split into even more categories
Each category can also be selectable as a genre so people can be as general or specific as they want
Categories can also have multiple parents from different grandparents (Hybrid Trap can fall under Dubstep/Riddim and Trap but is a single genre)
Also can set up a temporary system for beta testers to recommend new genres and what categories they might fall into, and also provide example songs to help categorize them properly
