Play music without using my phone

I'd like to replace all my Alexa devices with HomePod, but it doesn't seem like I can play Sirius XM or Spotify on HomePod unless I use my phone. I want to be able to say, "Hey Siri, play Sirius XM 'Channel Name'" without having open the app on my phone. Is this possible? If not, I will return my HomePod and continue my search for an Alexa replacement.
