Featuring Usher. Guetta told Billboard magazine it's "maybe the biggest song I've made in my life." He added: "We were in bargaining sessions for a while. Usher was saying, 'I need this record for my album.' I said, 'I'm sorry, I cannot give it to you.' After a while he called me back and gave in."

I can't win, I can't reign, I will never win this game.
Without you (Without you) (Without you)
Without you (Without you) (Without you)

I am lost, I am vain, I will never be the same.
Without you (Without you) (Without you)
Without you (Without you) (Without you)

I won't run, I won't fly, I will never make it by.
Without you (Without you) (Without you)
Without you (Without you) (Without you)

I can't take one more sleepless night.

I won't soar, I won't climb if you're not here I'm paralyzed.
Without you (Without you) (Without you)

A song simple and plain, repeating an old message retold a thousand times everywhere: Life without you makes no sense, I need you. But it is also a relief to find a simple song saying what we feel or have felt. Today's lyrics are often so sophisticated and cryptic that no message reach us and they need lots of explanations and context to find out that there is a message there after all. Simple songs are a blessing and usually touch us deeper because we can easily relate.
