Here's my prediction for next week:
Diamonds is falling fast. Scream & Shout WILL pass Rihanna. No huge change in the top 5 other than that, unless JT can somehow climb from #84 to #5. That's very unlikely as of right now, because he is already falling on iTunes. Suit & Tie had a lead of 1.0000 to 0.3425. That's huge, but now the lead is 1.0000 to 0.71888. He's falling fast. He also had a HUGE debut on radio, but will suffer from the rolling effect next week. Scream & Shout should have a free ride into the top 5 (#5) next week. Unless anything big changes from now until next Tuesday, this is how it should turn out.
