If there’s music playing and there’s a HomePod in the room, chances are that music is coming from HomePod. But there may be times when you’ve got some background music coming from another source (your TV, say) and you want to identify the tune.

I am used to asking Siri on my iPhone to identify background music. Typically, I’ll fire up Siri and say:

What song is this?

But trying to get HomePod Siri to identify a song playing in the background proved tricky. I tried everything I could think of. No dice.

Fortunately, 9to5Mac’s Benjamin Mayo figured this out. To ask HomePod’s version of Siri to identify a background song, say:

Hey Siri, Shazam this.

Works every time. Weird to me that none of the more standard ways work. I hope we don’t end up with a Siri dialect problem, where users have to remember which command works on which version of Siri.
