Music on your keys. Global keyboard shortcuts for the Spotify, YouTube Music and YouTube web players (open.spotify.com, music.youtube.com, www.youtube.com) in Chrome, plus a small now-playing popup with a clickable queue. Runs as a tray icon and works no matter which window has focus, so you never have to switch to the browser to skip, pause or check a song.

Previous behaves like Spotify's own button: restarts the current song if you are a few seconds in, otherwise jumps to the previous one.

Two layers:

1. Windows media session (no extension). Chrome publishes the playing tab to Windows as a media session. The app sends next / previous / play-pause to it and reads title, artist, album and artwork from it. This covers Spotify, YouTube Music and YouTube alike. Falls back to virtual media keys if no session exists.
2. Chrome extension (optional). Tiny unpacked content scripts run inside open.spotify.com, music.youtube.com and www.youtube.com and talk to the tray app over a WebSocket on 127.0.0.1:47321. They read the queue/playlist panel and click the site's own shuffle / like / volume / repeat buttons. Without it, the popup shows only the current track and the extension hotkeys show "Chrome extension not connected".

No Spotify login, no Web API, no Premium needed. When several sites are open the extension follows the tab that is actually making sound.

Requires the .NET 8 SDK (the script looks in %LOCALAPPDATA%\Microsoft\dotnet first, then PATH).

.\build.ps1

This publishes a single yuecontrol.exe, copies it and the extension folder to %LOCALAPPDATA%\yuecontrol, registers it under HKCU\Software\Microsoft\Windows\CurrentVersion\Run so it starts with Windows, and launches it. Use -NoAutostart or -NoRun to skip those steps.

1. Open chrome://extensions
2. Turn on Developer mode (top right)
3. Click Load unpacked and pick %LOCALAPPDATA%\yuecontrol\extension (tray menu "Set up Chrome extension..." opens that folder and copies the path)
4. Reload the open.spotify.com, music.youtube.com and www.youtube.com tabs

The tray menu then shows "Chrome extension: connected". Chrome shows a "disable developer mode extensions" bubble at startup for unpacked extensions; close it.

After every rebuild that touches the extension folder: open chrome://extensions, click the reload arrow on "yuecontrol bridge", then reload the music tabs. Chrome does not pick up changed files on its own; a stale content script answers "Unknown action ..." in the popup.

Clickable queue. Click a row in the popup to jump to that song. The popup stays open while the mouse is over it. Clicking the top part (cover, title) dismisses it.

Queue and the side panel. Spotify only renders the queue when its Queue panel is open. If the panel is closed, the extension opens it, reads it, and closes it again (a brief flicker). It then remembers the list and only re-reads when the current song is no longer in it, so most skips do not flicker. Keep the Queue panel open in Spotify to avoid it entirely.

Right-click the tray icon, choose "Edit hotkeys (config.json)...", change the bindings, save, then "Reload config". Format is Modifier+Modifier+Key, for example Ctrl+Shift+Space or Win+Alt+N. An empty string unbinds an action. Modifiers: Ctrl, Alt, Shift, Win. Keys use .NET Keys names (Right, Space, F9, N, PageUp, digits...).

Other settings in the same file: PopupSeconds, ShowPopupOnAction, QueueRows (default 5), VolumeStep (0.1 = 10%) and BridgePort (must match PORT in extension/background.js).

• "Chrome extension not connected": extension not loaded, Chrome not running, or the service worker is asleep. It reconnects within 30 seconds; opening chrome://extensions and clicking the extension's "service worker" link wakes it immediately.
• Shuffle / like / volume do nothing: the site changed its page structure. Selectors live in extension/content.js (Spotify), extension/ytmusic.js (YouTube Music) and extension/youtube.js (YouTube). Note YouTube's like button needs a signed-in Google account.
• Port in use: change BridgePort in config.json and PORT in extension/background.js, then reload both.

Right-click the tray icon, untick "Start with Windows", then Exit and delete %LOCALAPPDATA%\yuecontrol. Remove the extension from chrome://extensions.
