We've had other girls this year make an appearance based more on popularity than success and Kristina is another of those. She was exceptionally popular this year coming in the top places for hits alone, and that has seen her finish in 5th place on the top list.

Kristina has never been close to making the Top 25 before, so crashing in at 5th this year is a surprise. Her huge popularity this year has outstripped previous hits, since she first appeared in September 2016
