MixMusic Free and Open Source Desktop App CookApps CookApps Marketplace

Overview

MixMusic is a fast, native cross-platform desktop music player unifying YouTube Music and Spotify inside one lightweight Go binary. Built with MyGo native GPU windowing (zero Chromium/Electron overhead), MixMusic combines both streaming catalogs into unified search results, mixed cross-service playlists, synced & romanized lyrics, a 10-band equalizer, offline audio caching, and a sandboxed TypeScript/JavaScript plugin ecosystem.

How It Works

MixMusic operates through structured, deterministic execution stages:

Dual-Catalog Unified Search: Searches YouTube Music and Spotify simultaneously with play counts to distinguish original studio masters from covers, working immediately with zero account required for YouTube Music.

Interleaved Crossfade Queue & Mixed Playlists: Queues Spotify and YouTube Music tracks inside one shared playlist with crossfading, loudness leveling, 10-band EQ, and auto-continuing radio.

Pure-Go Native GPU Audio Engine: Draws every interface natively on the GPU via MyGo with pure-Go Opus, AAC, and AC-3 decoders, synced lyrics (LRCLIB/Unison + kagome kanji-to-romaji), and process audio loopback visualization.

Four Layouts, Fourteen Themes & Plugin Sandbox: Switches between Blend, Expressive, Crate, and Tiles layouts alongside Sobek-sandboxed JavaScript community plugins and Material HCT cover-derived palettes.

Key Technical Features & Capabilities

Dual-Service Search & Mixed Playlists: Searches YouTube Music and Spotify side by side, disambiguating studio releases from covers via view counts while interleaving tracks from both services into one continuous queue.

Zero-Account Instant YouTube Music & Optional Spotify: Plays YouTube Music immediately on launch with no sign-in required, and supports Spotify playback natively, via Spotify Connect, or matched seamlessly to YouTube Music audio.

Pure-Go GPU Rendering & Custom Audio Codecs: Ships native Opus, AAC-LC, AC-3/E-AC-3 decoders, Kaiser-windowed sinc resamplers, process audio loopback visualizers, and offline encrypted credential storage in one native executable.

Layouts, Themes & Typed Plugin Marketplace: Customize appearance with 4 responsive layouts (Blend, Expressive, Crate, Tiles), 14 built-in themes (plus Material HCT cover-extracted palettes), Last.fm scrobbling, Discord Rich Presence, and community plugins.

Troubleshooting & Common Issues

Issue: macOS reports unverified developer quarantine warning on first open.

*Cause*: Upstream macOS release binaries are not yet notarized by Apple.

*Resolution*: Open via System Settings › Privacy & Security › Open Anyway or run xattr -dr com.apple.quarantine /Applications/MixMusic.app.

Issue: Audio stream fallback required on restricted YouTube tracks.

*Cause*: Certain encrypted streams (e.g., children's content) require external resolver extraction.

*Resolution*: Install the managed yt-dlp companion binary directly inside Settings › Playback.
