Those who enjoy the public humiliation of standing on a stage and drunkenly singing in front of a bunch of other drunks tend to have a go-to karaoke jam. You know, the one song that makes the stranger at the bar tell you that you could totally make it on, oh, Karaoke Battle USA. But "Jesse's Girl" (or whatever your standard) doesn't always best capture the mood. Sometimes you hit the karaoke bar feeling somber or sad; sometimes you're eager to impress your date, your friends, or your gangster associates; sometimes you're just trying to have some wholesome fun with your niece go horribly, suggestively awry. So as a public service, we've turned to movies and TV to find the perfect karaoke songs for every occasion.
