What song should I sing for... (PLEASE ANSWER!)?

I was thinking of singing "My Vietnam" by P!nk.. it's a really old song by her but I really love it. And I know it's an old song. So do you think people would even bother watching it because it's so old?? I can sing a lot of P!nk songs actually. Because I think her voice is similar to mine, because of the range. And I can sing a lot of Taylor Swift songs too. And I was thinking of singing "Mine" by her. And I already sang, "Back to December", and "Love Story".. so yeah. I'm really stuck on what song to sing. But like I said before would they even watch/listen the "My Vietnam" cover??? What other songs should I sing?? Thanks in advance! No RUDE ANSWERS PLEASE :) Thanks :)
