Apple has confirmed to the Buzzfeed publication that the new device will add Siri support for Apple Music from the beginning of next year. Therefore, you will be able to use the Apple TV remote control to search for and play the songs that you want. Brendan Klinkerberg said the following:
"Apple confirmed to BuzzFeed News that Siri is coming to Apple Music on Apple TV at the beginning of next year. This means that using the Apple TV remote control, people will be able to say, “Play ‘Hotline Bling’” or “Play the newest Taylor Swift album,” and Siri will take it from there."
Those who already received their new Apple TV have praised Siri’s universal search feature, which allows system-wide searching for video content.
By extending Apple TV’s universal search to Apple Music, Apple basically turns the streaming box into a voice-controlled music player. Thus, the device becomes the entertainment center of your living room, taking care of your video, gaming, and music needs.
Up until now, Apple Music has managed to attract about 6.5 million paying listeners. While this number makes it the fastest growing music streaming service ever, it's still far behind industry leader Spotify, which has more than 20 million paying subscribers, and an additional 55 million ad-supported free listeners.
