Guy singing romantic lyrics?

The guy I like has this tendency to randomly sing along with romantic lyrics he hears on the radio (or play a romantic-ish song) and look right at me as he does it. Or he seems to start unconsciously, falter awkwardly as he realizes (?) what he's doing, then sing louder.
Uh... curious as to what you guys think? Is that normal flirting or what in your opinion?

Once we were with friends and he said "hey I want you to listen to this one song" to me and put on a song that went "if you love somebody better tell them while they're here" and I looked up as I realized what the lyrics were saying and I literally stopped because he was looking down at me with this really vulnerable look in his eyes and I had to actually remember to look normal because there were people with us.
