Need help finding program

A long time ago I was watching attack of the show and one of the hoost showed this program that automatically labels songs and puts all the labels on it thta itunes use. Because I have a lot of songs with a crappy label on them and there in itunes. But they are missing labels like Albums and Artisit and Genere. But on attack of the show they showed a prog. That automatically puts a label on it. Lol if anyone knows what program this was or a program like it please tell me thanx.
