I love this question, and I want to ask it more often. It’s an infinitely better question than, “What kind of music do you like?” That question is way too broad. It’s like asking what kind of food you like or what you like to do in your free time. There are too many possible answers, and it’ll leave the recipient of the question grasping for air.
Conversely, the question “What’s your favorite song right now?” is specific, topical, and fairly easy to answer. I say “fairly easy” because if you’re like me, you’re not all that good with song names, but you might be able to whip out your phone and find the answer on your “recently played list.” But I tend to think that at any given time, most people have one song that they’re playing over and over.
For me, that song right now is “I Will Wait” by Mumford & Sons. But I’d really like to know your answer to that question. What’s your favorite song right now? Pick one song. (This is a skill, to pick only one. You can do it.)
