Because of the fact that it's country influenced and country music isn't popular outside of North America. All things considered the BTW era was a success.
I'm just saying it wasn't the major WW success homegirl was claiming it to be.
Ask a random person in the street to sing "Judas" or "Marry The Night"
Ask a random person to sing "Rolling in the Deep" or "Call Me Maybe"
Tell me your results
I want Nicki Minaj to flop this year because her ego just got way too big way too fast. She hasn't really achieved anything that extraordinary to be acting the way she does.
And Ke$ha too. She should have stopped at We R Who We R
On topic: She will flop.
Off topic: I've been listening to a song by her for an hour, so I clearly don't wish for her to flop, I know she will.
Was that so hard ?
She has 5 films and an album coming out this year... she will also probably be filming more films this year so no, she won't flop. You are just going to have to deal with it tbh.
They can sing Born This Way or The Edge of Glory though. Rolling In The Deep and Call Me Maybe were the respective first singles for their albums. Who can sing any of Carly's other singles??
I'm sure they know the top 10 hit Good Time. You really don't want to go there with Carly girl.
