All the major songs like Somebody that I use to know, Young, Glad you came, Call Me Maybe are peaking and songs like where have you been, payphone and scream will have peaked by the time Dark side's in the top 10.
This can have a smooth sail going to the top since it won't have any major competition.
The thing is, radio isn't ready of letting go of Stronger. That song is so freaking huge and I still hear it all the time on the radio that I'm getting tired of it.
But either way I don't think it's possible for this song to flop especially with the sentimental cheesy video it has. The video may have been a turn off for the hardcore fans but we all know that people are going to eat this **** up.
