On the Christmas displays, I'm less annoyed about things like craft stores or home improvement stores putting out crafts and decorations early- some people need time to prepare.
So, I'm willing to vote for Rev's proposed solutions, so long as they get a special post-Halloween, pre-Thanksgiving carve-out.
If you need more than a month to prepare, buy it the year before.
Also, on the repetitive Christmas music, there are literally thousands (probably 10s of thousands) of versions of a myriad of Christmas songs: Choral, solo, orchestra, solo instrumental, quartet, brass, wind, strings, accordion, organ, piano, duets, trios, etc...
You could go the entire Christmas season with Christmas songs playing round the clock from Dec 1 (or the day after Thanksgiving, if you want to go early) to Epiphany (if you want to extend the season) and NEVER listen to the same song twice. Instead we get Mariah Carey's "All I want for Christmas is you" and John Lennon's horrific "So this is Christmas" and Paul McCartney's terrible "Last Christmas" and Dan Fogelberg's horrid "The Same Old Lang Syne" played every single hour on a continuous loop.
It's no wonder people hate Christmas music. Even the songs that DON'T start out as terrible get on people's nerves.
