Zack Collins was just a kid who liked singing about Mexican spices in catchy jingles until someone came along and told him he had a gift. Soon enough, Zack became a star because of his adoration of Taco Bell's Nacho Fries ... and, of course, his smooth ballad "Chasing Gold" dedicated to the cheesy dish. His passion turned into a phenomenon and Zack was feeling on top of the world until he read three words in a magazine: Limited Time Only. Nothing can last forever, be it a serving of Nacho Fries or the career of a passionate young musician. But, like Zack, perhaps it's time Taco Bell enthusiasts start chasing gold.
