I can see it like this
Rihanna
Lambert
lady Gaga
timbaland
Leona (from previous week)
Britney
Rest I dont know but probably Carrie and Taylor remaing in the top 10
I really think Rihanna will come out on top. "Russian Roulette" is just the first single, and knowing her history with Good Girl Gone Bad and it's many successful singles, we can expect there to be even more incredible songs. Also, we've been waiting a lot longer for new Rihanna material. Combine that with the fact that some people are losing their lust for GaGa (even though she's an incredible artist), and the fact that The Fame: Monster is essentially just a re-release of The Fame (though 8 new songs is quite generous), the top release of the week is most likely going to be "Rated R." My vote goes to Rihanna.
I really think and hope Mary J. will do it. Even though her singles haven't performed well in years, she still has a very large fanbase. Plus, she's the most talented out of everyone else
I have to go with Adam, just because of him being on American Idol. But If not it will go to Rihanna. I'm quite sure Kris will remain in the top ten for that week.
