What's great about finding songs with the assistant's help is that you don't have to browse the app for a title or an artist, which you might not always know. You could, say, ask Alexa to "play that new single by" a particular artist or play that song with so-and-so lyrics. Alexa will also play songs depending on what you need them for, whether it's for a road trip, to get you in the mood to run or to help you relax at night. The voice assistant is now live for both iOS and Android -- just update your app to get access to Alexa on your phone.
