if y'all dont want party in the usa to be number 1, then just buy 3 again and again or gift it to a friend or something so that it can number 1 again. just don't sit their and complain, do something about it, get 3 back to 1!!
^That's what I'm hoping! All three versions combined should be pretty good sales total... sadly they haven't been that high all week. I hope they stay like this or go even higher this week so they have a chance at #1 on the Hot 100. Maybe the hype of Rihanna's new single will push this even higher!
That shows how many ppl didn't bought their album!
