When listening to a song from your music library on iPhone and iPad, it used to be possible to ask Siri to “rate this song five [or whatever number] stars,” and the virtual assistant would do so without fuss.
This ability to rate songs in the Apple Music app with Siri was introduced way back in iOS 8. Listeners usually rely on the function to give songs in their library a rating when they’re listening handsfree via CarPlay, exercising while wearing AirPods, or making smart playlists based on ratings.
