HomePod mini randomly playing music on its own.

Is my HomePod mini being hacked or what? Since last night it started randomly playing music by itself, woke me up in the middle of the night with a random song, not even in my playlist. I had to unplug it and leave it like that because it’s impossible to stop it. I mean you can stop it for about 30 seconds or so, it listens to commands, but it doesn’t matter, because every time it starts again on its own.
