When is a song more than just a song? Among many possible answers, it is more than a song when it begins to change the very sound of the artist that releases it. Bruno Mars released It Will Rain in September of 2011, a song that is quite unlikely many of his other hits. Sporting a slicker, more modern sound, it seems more like the work of other artists. Despite the rather large departure from his typical musical stylings, though, It Will Rain has become a hit.
