Tell me why... there are so many songs about Monday

You've got New Order's "Blue Monday" (one of my all-time fave songs):



You've got the Boomtown Rats' "I Don't Like Mondays," the Carpenters' "Rainy Days and Mondays," Fats Domino's "Blue Monday," the Bangles' "Manic Monday"



and, of course, Hank Williams Jr.'s theme for Monday Night Football:



And those are but a handful of the odes to Monday, as this Amazon.com list of "Monday songs" can attest to. I believe only Saturday is more popular. (And yes, there's a list for that, too.)

Hoping you are not having a blue or manic Monday.... (Btw, speaking of blue or manic Monday, anyone planning on watching or TiVo/DVRing Oprah's Sarah Palin interview later?)
