DEMO: https://youtu.be/dVlqUsrqO2M

A RESTful web application using Musixmatch and Spotify API to generate trivia questions on music artists. A user can log in through spotify using OAuth2 setup in Spring Security. Artist information is stored in the database for the purpose of developing questions for users, with the additional functionality of limiting external API requests. Database also keeps track of all games played.

Note 2: This application is intended for premium Spotify accounts due to licensing issues with record labels.

Game modes include:

• Identify song from 30 second audio segment

• Identify song from lyrics (Functional, but unable to scale due to rate limiting issues. disabled)

Data Flow

Database (New v 1.0 Release)

Simplified the question and game history storage with expansion for multiplayer in mind. More noticeably, storage of Spotify media metadata is implemented. This is a necessary transition due to the limitations of API requests. Client side instances will check the database for artist information before hitting Spotify's API.
