Gimme More (Femme Fatale Tour Studio Version DEMO)

This is only a demo of my version of "Gimme More" from Britney's Femme Fatale tour. I didn't add everything, like some of the instruments and stuff in the background, but I have pretty much the basic things that are in the song. Also, it's not completely finished, so do you guys think I should finish it? Tell me what ya think!
