Ariana Grande, "Pink Champagne" (2013)
Kesha helped write "Pink Champagne," which was never officially released for sale — Grande posted the track on her YouTube account as a thank you to fans when she reached 10 million followers. "I hope you enjoy this fetus record of mine," she said at the time. Though Grande's debut album was dominated by Nineties R&B homage, "Pink Champagne" hints at an alternative direction that she could've taken. Like Cyrus' "The Time of Our Lives," this record emphasizes a pounding pulse, with some of the forceful neo-doo-wop elements that were so successful recently for Meghan Trainor.
