I wouldn't be so sure. Coldplay seems to be doing stadiums everywhere vs. Rihanna doing arenas in North America. But on the other hand, i believe Rihanna will be adding more stadiums to this list + she has higher prices in Europe as far as im concerned. It'll be a very close race either way this goes!
*giggles hysterically @ two big acts. when have they sold out stadiums?*giggles hysterically* how many WW UWC global hits do they have? how many WW albums have they sold? *giggles hysterically*
