Is Christmas being 'advertised' too early every year?

I hate when shops and supermarkets put up christmas decorations and start playing christmas music the day after halloween!! They do it every year and its way to early! Dont get me wrong, i love christmas and the celebrations coming up to it but shop should wait until at least the end of November to start playing christmas carols! I fell so sorry for people working in supermarkets who have to listen to the same carols over and over again! It must do their heads in!
