Apple TV Gen 4 - Siri and Music

Hello there, Harvey.

It sounds like you may not be in a region where Siri may not be currently available for use with your Apple TV (4th generation). The following Knowledge Base article provides more information in regards to using Siri:

Use Siri on your Apple TV (4th generation)

Here's where you can use Siri

Siri is currently available on Apple TV (4th generation) in these languages and countries: English (Australia, Canada, UK, US), German (Germany), French (France), Spanish (Spain), Japanese (Japan).*

{...}

*Siri availability varies by country and language. Apple TV (4th generation) ships with the same remote everywhere. In countries and regions that support Siri, the remote is called Siri Remote. Elsewhere, it’s called Apple TV Remote. Siri works on either remote as long as your Apple TV (4th generation) is set up with a language and country
that supports Siri.

Thanks for reaching out to Apple Support Communities.

Cheers.
