## Overview

Signature Music is a static, client-side music player. A listener opens the page, browses curated tracks, selects one for playback, and can manage favourites and playback options or download and share the current track. The sampled JavaScript shows the player controller coordinating track selection, playlist updates, audio playback, and Media Session metadata; the README documents additional capabilities whose specific wiring is not shown in the excerpts.

Main entry points: [`script.js`](https://github.com/haiere/signature-music/blob/main/script.js) (Player controller), [`index.html`](https://github.com/haiere/signature-music/blob/main/index.html) (Player page), [`data-song.js`](https://github.com/haiere/signature-music/blob/main/data-song.js) (Track catalog), [`style.css`](https://github.com/haiere/signature-music/blob/main/style.css) (Responsive interface)
