# 🎵 Tetris Music Implementation Guide You are building this from scratch. No files exist. You must follow the 🎵 Tetris Music Implementation Guide before writing any game code. ## ✅ Features - Autoplays a full list of Tetris-inspired tracks - Displays the current track name for a few seconds when the song changes - Mute/unmute button is shown in the **top-right corner** of the screen --- ## 📁 1.
