Music app on my iMac starts on its own, even after I quit the Music App

I use a 27" iMac and am using Sequoia 15.5. Since last about a couple of months, even after I stop the track playing on the computer, the Music app starts on its own. This morning (NYC time), it kept on coming bak on several times. I even Quit the Music App, it still started up. I even tried to remove it from the Dock, but it still started up, came back up in the Dock. I also noticed that whenever the music started, the Seri sign would come up.though I had not said a word to awaken Seri. What can I do to rectify this annoying occurrence?
