Some of the greatest songs in the world all have conditional titles. Anything that starts with "If" is almost certainly going to be good. Here are two of Merle Haggard's greatest "If" songs, both of which coincidentally happen to be about December and Mondays and are thus particularly relevant to us. "If We Make It Through December" is a very good song; almost every song that is set at Christmastime but is not cheerful is…

I will go to my grave maintaining two things: that "Pancho and Lefty" is the saddest song ever sung in this wide and lonely world, and that Toby Keith is a congenitally underrated musician and person.

The best, the definitive version, against which all other versions are ranked: Willie Nelson and Merle Haggard.
