Christmas music is supposed to make people's moods positive, spend more time in the shops, spend more.
In fact, customers are getting annoyed with it, feel sorry for the workers, spend little time as possible (ie shop online) and force cheer (MH issues, worried about health of loved ones)
I did 18 Christmases in retail. I hated the Xmas music being played. The thing is we try to zone it out but when customers said something on the lines of "does this music annoy you", "what a dreary song" (such as Mud's Lonely This Christmas). Then we bloody heard it! Then because more of us worked outside trade hours, as had more delivery etc to do, the music was still being piped through the tannoy. As done centrally. We put something heavy on the call button on the tannoy to stop it. One day, a manager said we could put on our own music. We put a rock channel on a colleague's streaming app and that was good.
At least we have the songs sung by the actual artists. Some retailers play cover versions by unknown artists they are worse.
I think the reason many people hate Christmas music is no other time of the year, so few songs are played to death. Also not many new decent Xmas songs(thank you Simon Cowell) . If you buy a Christmas music album today and compare with an album released 25-30 years ago in a charity shop. The only song which is different is on the CS one it will have a paedo's Xmas song (clue GG) and the new one will have such as Destiny's Child's one.
Those who love Xmas music, I tell you now, work in a place that plays Xmas music all the time and you will hate it.
