Siri, Apple's voice-powered virtual assistant, is pretty musically inclined. She's been able to manipulate your music library for quite some time, letting you play specific tracks, albums, and genres with a simple command. Now with iOS 8, her musical powers have expanded even further.

For those with downloaded music on their iOS device, you can use Siri to rate songs in your music collection. While you're listening to a song, just access Siri via the home button and tell her "Rate this song four stars," for example. Boom, done. (This does pause the song while you interact with Siri, but only for a moment.) Rating your music can be useful for organizing your music library, and for creating smart playlists.

If you don't have much music downloaded on your phone, Siri has another feature you may find useful. In iOS 8, Siri can tell you what song is currently playing. If you ask her something like "What song is playing?" "What is currently playing?" or "Name that tune," Siri listens to the ambient sound around you, and thanks to Shazam integration, can identify the track and artist. This feature is super handy—far speedier than having to unlock your device, then navigate to the Shazam app to do the same thing.

Alas, Siri cannot delete that U2 album from your phone. But luckily we already explained how to do that.
