Muzo

Muzo is a feature-rich, privacy-focused YouTube Music client built with Flutter. It offers a premium ad-free experience with background playback, offline downloads, synchronized & karaoke lyrics, a modern gesture-driven UI, Spotify playlist imports, a sleep timer, and community sharing — with or without an account.

🚀 Key Features

🎧 Immersive Audio & Lyrics

- Smooth Word-by-Word Karaoke — Words in karaoke mode fill up with color gradually in real-time as the artist sings (running at a buttery-smooth 60+ FPS). - Line-by-Line Synced Sweep — Synced lyrics feature a progressive sweep effect across the text, coloring repeated lines sequentially. - Active Line Highlight & Scrolling — Active line slides slightly to the right and lights up. Scrolling or tapping a line glides smoothly rather than jumping abruptly. - Frosted-Glass Gesture Mode Lyrics — Transparent lyrics panel positioned above controls in the gesture player, letting you double-tap or swipe volume right through it. - Lofi Mode — Transform any track into a Lofi vibe with slowed speed (0.9×), pitch correction, and native reverb effects. - Multi-Language Audio & Quality Control — Detects and switches between available languages and streams in High, Medium, or Low quality. - Background Playback & Native Effects — Keep music playing with the screen off while utilizing platform-specific audio effects.

🕹️ Gesture Player

- Full Gesture Control — Immersive gesture-based player where album art fills the entire screen. - Double-Tap to Play/Pause — Toggle playback anywhere with an animated flash icon. - Swipe Navigation — Swipe left/right to skip tracks; swipe down on the left half to dismiss the player. - Frosted Volume Bar — Swipe up/down on the right half to control volume with a glass vertical bar and fill indicator. - Bottom Controls Popup — Glassmorphic popup with title, artist, progress bar, queue, lyrics, and favorite buttons.

🎨 Modern Adaptive UI/UX

- Dynamic Glassmorphic Themes — Premium styling in both Dark and Light modes. Light Mode features a beautiful, semi-transparent white tint (light glassmorphism) that adapts dynamically to the album art. - Contrast-Aware Elements — Status bar icons, player controls, progress sliders, borders, and menus automatically invert colors based on active theme for perfect legibility. - Big Screen & Desktop Optimization — Dedicated top search bar and profile dropdown menu for desktop, laptop, and tablet formats. - Sleek iOS-Inspired Forms — Rebuilt music upload/edit menus and notifications using modern pill-shaped inputs and circular badges.

📚 Discovery, Import & Community

- Spotify Playlist Import — Paste any public Spotify playlist URL to instantly import your favorite tracks. - Community Feed & Sharing — Search, stream, and discover tracks uploaded by the community in a dedicated global feed. - Artist Following — Follow your favorite artists and channels directly from their profile pages to easily keep track of them. - Smart Queue & Infinite Playback — Queue clearing successfully empties upcoming songs in auto-queue mode, and disables the clear button when only the active song is playing. - Offline Downloads — Download songs and videos for offline listening. - Recently Played Grid — Compact 2-column grid of recently played tracks on the home screen.

🛡️ Privacy & Accounts
