ScreenSleeves detects which music player is playing, and displays cover art and details for the currently-playing track.
ScreenSleeves displays the album artwork(s) for the currently-playing song with some details, even lyrics, in some neat, easy-on-the-eye ways (it has a number of themes). Perfect for downtime or parties.
Important Note Screensleeves has a long history as a screensaver. Security changes within macOS Mojave have made it impossible to continue as a true screensaver (which is a system plugin). The solution has been to put ScreenSleeves within its own 'standalone' app which emulates a screensaver. This has other advantages, such as displaying a small floating window when not in full-screen mode which users have asked for throughout its history. This standalone version replaces previous versions which are now unsupported and will not run on Mojave. It has a free trial, after which requires a license key.
Support for Music, iTunes, iTunes internet streams, Swinsian, Spotify, Airfoil Satellite, Snowtape, Ecoute, Rdio, Radium, Audirvana Plus, Hermes (Pandora client). Screensleeves detects which is playing.
