Music Switcher for VKontakte is a Chrome add-on that allows users to control their music using their keyboard and receive notifications about the current tracks. With this add-on, users can switch tracks using the media buttons on their keyboard or through a window that appears when clicking on the extension icon in the browser.

When a new track starts playing, users will receive push notifications with the track's title and artist. The push notification feature can be disabled if desired.

For macOS Mojave users who are experiencing issues with the media buttons not working, there is a simple solution. They need to go to System Preferences > Security & Privacy > Privacy > Accessibility and enable the checkbox for Google Chrome.

If users don't have media buttons on their keyboard, they can customize their own shortcuts in the extension settings. To access the settings, simply copy and paste the following link into the browser's address bar: chrome://extensions/shortcuts.
