## Overview

This Flask music-player application lets a user manage playlists and tracks in a browser, then play and organize the resulting collections. The main flow runs from the web interface through Flask routes to playlist operations, with playlist state persisted as JSON and uploaded audio stored locally. Separate capabilities include playlist administration and song copying, playback tracking and favorites, and sorting, shuffling, and reordering. The README documents these features; sampled source confirms representative route, persistence, upload, and data-structure behavior, but not every route’s wiring.

Main entry points: [`app.py`](https://github.com/rislan-moh-tm/music-player-dsa/blob/main/app.py) (Flask routes), [`static/js/main.js`](https://github.com/rislan-moh-tm/music-player-dsa/blob/main/static/js/main.js) (Player interface), [`adt.py`](https://github.com/rislan-moh-tm/music-player-dsa/blob/main/adt.py) (Playlist operations), [`templates/index.html`](https://github.com/rislan-moh-tm/music-player-dsa/blob/main/templates/index.html) (Player page)
