Arabesque has been shipped with macOS for quite awhile now, making it one of graphical default screensavers. What Apple seems to dismiss, however, is that they did not update their lines of screensavers since High Sierra.
Since High Sierra, Apple has introduced ‘universality’ to its set of media keys. All the absurdities aside, it means media keys are now open to work with any platform. So if you were planning to control iTunes or Spotify on the go, you may accidentally start playing a random video on a webpage instead.
