6 Women and 2 Men Who Would Sing Come on Over Better then Jessica Simpson
Women:

1) Miranda Lambert (the song does have a sort of out of control prarie fire quality,and Ms Lambert can deliver)
2) Trisha Yearwood (could work as a corrective/paratext to the slightly cryptic Garth Brooks single More then a Memory)
3) Faith Hill (because she does songs alike this in a way where southern politness infects public lust, and Simpson is playing up her southern charms here)
4) Tanya Tucker (because she needs a comeback single
5) Martina McBride (because it would have worked better as a torch song, and her last album attempted and failed at it)
6) Britney Spears (though her last album was genius, profoundly unhinged, the southern girl working thru the genres as an attempt towards redemption, fits Britney's narratives much then Simpson's)

Men:
1) Brad Paisley (because it doesn't have any of the creepy misogyny that is work is so infamous for)
2) Josh Turner (because he could make the song much sexier, much more desperate)

as it is, the song is weirdly sexless, and desperate.
