Every week, iTunes staff select a single from an up-and-coming artist and puts it on its homepage as a Single of the Week. Each song is only free for one week, and thereafter the price for it increases to $1.29. Previous singles included Pompeii by Bastille, Little Numbers by BOY, and even Little Talks by Of Monsters and Men.

This week, the single is : Made in America by Cimorelli
