Songfacts®:

• Written by Madonna, Justin Timberlake, Tim Mosley and Hannon Lane, this duet with Timberlake is lyrically about doing one's bit for charity. Madonna sings:
  
  You don't have to be rich and famous
  To be good
  You just gotta give more more more
  Than you ever have before
  
  Of course, the sexual connotation is undeniable.
• Justin Timberlake filled many roles for the Hard Candy album: songwriter, producer ... therapist? According to Madonna, working with JT was like going to therapy. "We kind of had psychoanalytic sessions whenever we wrote songs. We'd sit down and start talking about situations. And then we'd start talking about issues or problems or relationships with people," she told Interview magazine. "That was the only way, because you know, writing together with somebody is very intimate."
  
  Timberlake also co-wrote "4 Minutes," "Miles Away," "Devil Wouldn't Recognize You" and "Voices."
