Looks like "C'Mon" won't break Ke$ha's Top 10 streak. Everyone calls her a flop but you have to remember she has yet to have a solo single fail to reach the Top 10 in America...her trouble with album sales clearly doesn't come from failing to make songs that connect with the public.
"Carry On" deserves to smash and hopefully now radio will start to catch on as well. It looks like all three hits off Some Nights will be sleeper hits

But that's usually the way it is with alternative or rock acts.
