Since Applejack won the Canterlot Singing Competition by singing "Beat It" by Michael Jackson at the Canterlot High gym, she is nicknamed Applejackson. When Lyra Heartstring's video from her phone has gone viral in almost no time, that means trouble for Applejack. She only wanted to sing just for fun. Being a farming cowgirl is super easy for her, but being a rising star could entirely change her life forever. After she has performed at a few live concerts, she is nominated to sing in the Celebrity Showdown against Lady Rara, who is her childhood friend named Coloratura. Perhaps she and Coloratura have already forgotten about each other. Will they remember each other by the end of the Celebrity Showdown?
