The song is "Feels Good Lost" by the Broken Social Scene Wave Interference: "If a crest of a wave meets a crest of another wave of the same frequency at the same point, then the magnitude of the displacement is the sum of the individual magnitudes – this is constructive interference. If a crest of one wave meets a trough of another wave then the magnitude of the displacements is equal to the difference in the individual magnitudes – this is known as destructive interference." - http://en.wikipedia.org/wiki/Interference_%28wave_propagation%29
