The SiriusXM app can be accessed from the Flex streaming device and X Class TV as well as through the X1 hub for live TV. Say "SiriusXM" to your voice remote or look for it in your device's list of apps.

You will either have to sign up for a paid subscription or use your existing one to use the NBC Peacock app. If you sign up for a three-month trial, you won't have to pay for the Streaming Platinum tier.

There are over 400 channels in the Platinum tier, with 330 for ad-free music, two exclusive Howard Stern channels, and stations for comedians like Kevin Hart. The other two subscription packages for streaming only are more expensive but come with a more limited lineup of stations. You can see the full lineup of stations from the site, as well as apply filters to see how access varies depending on the plan you sign up for.

"With today's launch across X1, Flex and XClass TV, our customers can now enjoy all their favorite music channels, podcasts, live news and more from SiriusXM on the biggest screen in their home, seamless integration with all their other entertainment."

The first Google TV platform in 2012 made the SiriusXM app available on smart home devices. This includes smart TVs from Amazon, Sony, and others as well as streaming devices like Apple TV.
