it will change nothing this week
the only think that can make a differance is the radio now
If there is a 24 rollover affect then yes, it does matter. And even if it doesnt, if its close enough then the lead E.T. can build over S&M does matter(lead translating into thousands of sales)
I'm can't even joke on Ri, she knows this week is the last chance S&M has to go #1. This coming week will go to E.T. and in the following weeks Judas, TLS, and Girl will be picking up momentum.
I wouldnt be surprised if E.T. is number 1 this week, theres so many stuff we dont know based on how much copies are sold on weekends compared to weekdays, other retailer sales where its not a sure fire thing that one or the other is going to be #1.
