Marking a Song as a Favorite Hands-Free with HomePod, etc

It used to be I could say "Hey, Siri I love this song!" and Siri would reply "Ok" and something about remembering I said I liked the song. However, for the last couple of months(?) this doesn't work and instead Siri interrupts the flow, and says "OK, here's a station just for you" and just starts playing a different song entirely and a new "station"! This is infuriating, and I want to know how I can tell Siri I like/favorite a song hands-free with HomePod, etc so I can cook while I listen and mark songs I like.
