Facebook app name..please help ? ?

[Michelle]

What is the name of the facebook app where you can pick your top five of something. I used it awhile back but can never remember that name of it. . .

an example would be :
The topic would be : Top 5 favourite songs ;
there is a box to type in and when typing different recommendations will come up, when you select one a picture and the words will come up in one of the five spaces on the screen.


Does ANYONE know what this is called ? !!
