Years ago, Justin Timberlake wrote the song "Gone," below, for Michael Jackson. As the story goes, Michael passed on the song, so NSync went on to record it.
After NSync released the song, Michael called Justin and told him he loved the song and wanted to record it as a duet. Michael made it very clear he only wanted to record with Justin, not the other members of NSync. Justin says in the below clip that this was the first time he ever thought about doing stuff on his own.
