What is that song?

While we were in Puerto Rico, there was one song that we heard ALL THE TIME. In stores, every time we turned on the radio, just walking down the street. So now, of course, it’s stuck in my head, and I have no idea what it is or who sings it. Added to that, I don’t remember any of words, just that it sounded like a power ballad and has a lot of OOOOHHs in it. I’m on the case, though!
