Develop api server on Laravel 8

Just a backend, no frontend.

Laravel 8, PHP 8.

The project is a music service for business.
Music authors can download their works, organizations can register, make playlists, schedules, and listen to music.

The project is small. There is already written code that requires refactoring.

There is no hard time to develop, the main quality of the code.
