Pinkie Pie singing rock music
If somebody makes an animated rock opera, I think Pinkie Pie will the the #1 character because she is the most musical. But, she's not the only one. All of her best friends, Derpy Hooves, the Cutie Mark Crusaders and the Pegacorn princesses sing too. So, is there a way to make many more characters sing, even Gilda the Griffin who I think shall sing solo?
