MusicBrainz is a free music encyclopedia that is a public database of all the major artists, albums, and songs. It is a community-driven project, so anyone can contribute, including artists, producers, labels, and fans. The goal of the project is to create a comprehensive database of all the music in the world, which will include a complete catalog of all the major artists, as well as their albums and songs.

The database is a completely free, open-source project. You can download the app on your Android device and create an account. Once you have created your account, you will be able to upload your music, which will be stored in the database. The app will then allow you to browse through all the major artists, albums, and songs, as well as the different genres.
