What is the difference between music and a pleasant background noise which serves for entertainment while doing other things? If you know or want to find out then listen and discover. Remember that great music is always waiting to be discovered. Bach's cantatas were lost for 100 years, half of them were never found. Schubert never heard any of his symphonies played by an orchestra. Isn't the internet a miracle, allowing composers from centuries ago to be heard across continents from England to Brazil, from America to China. Enjoy.
