I don't really care if you want to play music in your car, or in your home, or in your ears, whether you're on the street or in the pool.
And I know that in some public areas, classical music is piped in to keep out the hooligans. Very clever.
That said, I can't abide by business owners who put ghetto blasters outside their shop, or worse yet have installed outdoor speakers, and play music loud enough to hear as you pass by.
Inside, fine. Outside, I will never buy anything from you, ever.
