Oh, the end credits rap. A product that pretty much lived and died in the 1990s, movie producers would take a big music superstar and have them recap the plot of the film you just watched -- in the form of a rap -- over the closing credits of the film.

And now, the art form is back thanks to the genius of Iggy Azalea and soundtrack composer A.R. Rahman ("Slumdog Millionaire"). The track, "Million Dollar Dream," recaps the plot of the Jon Hamm starring "Million Dollar Arm," which hits theaters on May 16.

Let's just take a moment to reflect on the glory of end credits raps. They hit their nadir with Will Smith's ascendance to the official, state-sanctioned title of "Mr. July 4th," when the multiple threat dominated the Independence Day box office several years in a row. "Men in Black," it's sequel "Black Suits Comin' (Nod Ya Head)" and the title track from "Wild Wild West" all were massive successes* on the accompanying soundtracks.

The phenomenon wasn't just limited to Big Willie Styles, though. Vanilla Ice's "Ninja Rap" closed out "Teenage Mutant Ninja Turtles II: The Secret of the Ooze," while M.C. Hammer threw his own puffy pants into the ring with "Addams Groove" from the "Addams Family" movie.

End credits raps seemed to die out as rap grew as a genre, though, with films instead having a related song rather than one that reiterated the plot point by point as the credits rolled. What if you forgot what happened in the movie the second the titles came on? What were we supposed to do then?

Happily, they're back with "Million Dollar Dream," and we can only assume they're here forever. We can't wait for the end credits rap on "The Fault in Our Stars." That's gonna be sweet.

The "Million Dollar Arm" soundtrack will hit stores on May 19.
