Creating multiple elements of the same fields into an array with FormBuilder

Hi, Im trying to work out a way to create multiple elements of fields as arrays into a form. Ie I want the fields to be grouped in a row and then i can list say 5 rows of these elements. To give you an idea what i am doing. I am trying to be able add Track Titles for albums, but i would like to list more than one item at a time, say we had 10 tracks 10 rows. So in each row i want to display the title, a list menu of artist names from a DO and the duration. Any help with this would rock thanks.
