remix wit wiz is the smarter choice cuz hes the "it" rapper and if we havnt learned by now what a remix wit a rapper can do then just ask katy & kanye
a remix wit britney wud be a waste tbh, however a new song wud be amazing considering that brit has HUGE front loaded sales and wit rihanna in the track the song can be a HUGE radio single and with both of them the song can have longevity.
thats how i see it
