I saw the above comic at XKCD, and it made me laugh in that rueful way that we Gen-X types tend to laugh about the cultural dominance of the Baby Boom generation. It's funny because it's true.
What's also true is that there's only one religious song on the "Baby Boom" chart area, and only two on the whole chart. Which is one of the reasons that being bombarded with so-called "Christmas music" on radio stations, in stores, and in public places from about the end of October until noon on Christmas Day is so deeply, deeply annoying.
It's not that I want to be racing through some ugly ShopMartGoGetBuyStore while being serenaded by religious songs, either; in fact, there's little in life that's more jarring than doing some Christmas shopping while hearing some electronically-enhanced minimally talented pop star jazzing up Silent Night or something similar. To focus in on the Babe of Bethlehem is to realize with a sickening sense of shock that our culture is absolutely mad in its consumerist frenzy which just happens to coincide with that holiday Christians call Christmas.
At least it's the secular songs that most often get parodied in commercials, particularly car commercials. No, I don't want to celebrate "Happy Honda (tm) Days," and no, I don't think the current Nissan (tm) sale is "The Most Wonderful Sale of the Year." But it would be a heck of a lot more offensive if someone started singing "O Come, All Ye Shoppers," "What Deal is This?" or "Savings We Have Seen on High," or some such stupidity.
There are nine more days left of Advent, which means nine more days of being surrounded by the verbal equivalent of cheap tinsel. After that, when the Christian world actually begins celebrating the Christmas season, the stores will be busily dealing with Christmas returns and gearing up for the next big retail holiday, the January Clearance/pre-Valentine's Day Sale. But at least we won't be bombarded with special schlocky songs during that retail season; at least, we'll only be bombarded with the usual schlocky songs that stores play for our ceaseless torment.
