It's a bit late to be tagged in anything really since my list is kinda solid, also please stop commenting "this was from 2013". Most everything from 2013 is eligible, deal with it!
#21 - Bailando - Enrique Iglesias ft. Sean Paul, Gente de Zona and Descemer Bueno
Fun Fact: Natalie Anderson wins Survivor San Juan del Sur
Hint for #20: The artist is very Evanescence-esque.
