Well for 2014 with weeks

 

USA- 20 (Idina Menzel- 15, Band Perry- 1, Lea Michele- 1, Lana Del Rey- 3)

England- 2 (Molly and La Roux- both 1 week)

Sweden had hauled themselves up to 3rd in my table a few weeks ago but Australia have overtaken again with Sheppard x 2 and The Veronicas! Talk about two countries that punch significantly above their weight!
