Auditions

So I'm trying out for my schools talent show/show case thingy where I'm going to be doing a cover of a song. I'm not sure what song I want to do and every time I sing the options for my friends/family they can never decide on which one they like best, so I was wondering if you guys would be interested in me posting some videos (without my face of course) and vote to help me pick a song? Or if there's other singers out there that would be willing to give me some tips?
