hiphop/rnb song

So i im looking for a newer sounding hiphop/rnb (?) type song, i have googled about any part of the lyrics that i can make out without a result

The refrain goes like this:

Never thought you could get down like that
*somethingsomething*
*something*-drop it down like that

if i get a little closer to you
if you keep on doing what you're doing
if we keep on moving at the rate we're moving
then we might just end up *something...*

Also in the start i believe theres some mumbling about "insomniacs", can't really make out much more.

Any help would be appreciated!

the first part sounds like a part of "independent women" by destiny's child....
But I think that is not the right song as the second part does not fit at all... Just thought I'd let you know...

Thanks aiyana but the voices are all male

I'm looking for this song,too
can sombody help me ??
