This thesis is about Bink’s Melody, a web app that lets users listen to music and make playlists. It's built using JavaScript, Firebase, and the Jamendo API. Users can sign up, log in, and create or manage their own playlists while exploring songs from the Jamendo library. The app uses Firebase for login, data storage, and email verification. It also has a music visualizer made with the Web Audio API that reacts to the sound while playing. The goal of the project is to make a simple and fun way for users to enjoy music through a clean and easy to use web interface.
