Such songs are quite like one of those old cities. Its buildings and monuments at once enamour the casual visitor. Yet the deeper one ventures, the more they discover. The more time one spends at and explores the place the more one learns about its inhabitants, its history, and the greater is the aura cast by the ages past.
Become conscious of a song’s composition; the instrumentation, its orchestration; the vocals, their lyrics, their meaning; the context, and feel the blood surge through every last vein on your body as you listen to a work of art. The experience is, in two words, truly magical.
