Now this one is really testing me. A song you hear often on the radio? The problem is : there is only one music show that I listen to on the radio - Bob Harris Country, and he's not really known for playing the same song more than twice.
My only other music radio listening is in the gym while getting changed - Capital Radio, and I am searching my mind (and their playlist) for a clue.... and I do recall hearing this a few times.
But I dissemble. Perhaps you will be surprised, dear reader, to know that I have seen Justin Bieber in concert (!). He was the support act when we went to see Taylor Swift. I have to admit - he was very good. Even if he is only eleven.
