This document discusses using gamification in the design of the Genie music service. It outlines the MDA framework, which describes mechanics, dynamics, and aesthetics. It then analyzes Genie's implementation of 7 core game mechanics: points, levels, leaderboards, badges, onboarding, challenges/quests, and engagement loops. While Genie incorporates many of these elements, the document provides recommendations for how it could further improve gamification, such as adding experience points and rewards for completing missions. The goal is to enhance users' emotional experiences and engagement with the service.
