Are whales making music?
As with birdsong, it depends what you mean by music. I've lined up this recording so that the theme in mm 1-11 lines up with its repetition in mm 33-43. Not only is this laid out in lines of 16 measures (similar to human-created music), but several elements seem to fit within the measure boundaries-- for example, measures 24, 35, 39, 46, 62...
Perhaps it's our human tendency to see patterns where they may not exist, or perhaps this whale's song really has a deliberate sense of measures and verses.
