Deeper music integration in Meta's Instagram app is being explored by Meta and Spotify. According to recent research, businesses are testing a feature that lets users use Instagram's Notes to share the music they're listening to continuously. Reverse engineer Alessandro Paluzzi, who frequently discovers unpublished features while still developing, was the first to notice the new capabilities. Though businesses like Meta and Spotify often test new ideas, the discovery does not guarantee that the function will be made available to the general public anytime soon.
