Then there are the stores, With apologies from the veer. From my travels.....
Selfridge's Department Store. Oxford Street, London. Full blown decorations inside and in the windows. I snapped pictures on my phone on October 29 a few years back. Canadian Tire, West Island Montreal. Christmas decorations up in September. About five years ago.
I personally LOVE Christmas and the Holiday season....but those two examples are more than a little extreme, IMHO. As for the music, I don't care when it turns up on radio. I don't listen to it. I usually start playing my own mixes (about 300 tracks) on my 15 year old laptop, which now exists exclusively as a Spotify jukebox. Then feed it to my FM modulator, which has a range of about one block on 92.1. And yes, a couple of my neighbors always ask me when I'm going to crank it up.
