Spotify Friend Activity is a free Chrome extension developed by Jack Weatherford that allows users to view their friends' listening activity on Spotify's web player. By adding a panel to the web player, this extension provides a convenient way to stay updated on what your friends are listening to.

To get started, simply add the Spotify Friend Activity extension to your Chrome browser. Then, open a new tab and navigate to the Spotify web player. Login with your Spotify account and make sure that you are following the Spotify users whose activity you want to see. Additionally, ensure that your friends have enabled the "Share my listening activity on Spotify" setting in the Spotify desktop app and have listened to music on the desktop app within the last week.
