If the average Itunes listener just previews the song(assuming they have a nice size advert in new music) then i'm sure it will destroy the itunes sales of Go Girl. Go Girl sold about 14,800 first week. This song is easier on the ears for more genres. I have my accounts ready and cards in hand! The video being released 1st will also help!
The Billboard thingy happened to Britney's "Circus", too. It's a glitch in their pages. "Never Ever" will peak at that number in the Bubbling Under charts.
