The song is that of a man telling a woman (from Málaga, Spain) how beautiful she is, and how he would love to be her man, but that he understands her rejecting him for being too poor.
Bonus – What is up with those strings? The answer below the fold dear readers.
Rolling shutter is a method of image capture in which a still picture (in a still camera) or each frame of a video (in a video camera) is captured not by taking a snapshot of the entire scene at single instant in time but rather by scanning across the scene rapidly, either vertically or horizontally. In other words, not all parts of the image of the scene are recorded at exactly the same instant. (Though, during playback, the entire image of the scene is displayed at once, as if it represents a single instant in time.) This produces predictable distortions of fast-moving objects or rapid flashes of light.
