I CANT HOLD THIS QUESTION ANYMORE

I have one question for all of you that listen to current music. In the song 4 minutes by Madonna ft. Justin Timberlake, the most questionable line in that song is "we only got 4 minutes to save the world". Why? You may ask, I am about to preach on................... If you only have 4 minutes to save the world, why on earth would you waste your time singing. Does your singing help to save the world or are you stupid and trying to make your life into a musical. And another thing that line makes Madonna and Justin Timberlake sound like they think they are superheros or something.

Madonna: Oh no Justin we only have for minutes before the world explodes........
Justin: What ever shall we do?
Madonna: Well time is waiting, and there's no hesitating.
Justin: You know what this means, we must do what we were born to do in order to save the world........
Madonna: What's that?
Justin: We must sing!

Wow that couldn't have ended well after those 4 minutes of complete idiotic actions. Whatever their loss.
