One of this summer's biggest artists, Robin Thicke, is holding strong in the top spot with 'Blurred Lines,' but will one of the other artists dethrone him?

This week, Katy Perry's 'ROAR' and Enrique Iglesias' 'Turn the Night Up' join the rankings. Seeing as how both artists are known for their radio-friendly tracks, we wouldn't be surprised if one of them made it up to No. 1!
