Timberlake struggles to write songs

Justin Timberlake says he cannot find the time to write his own songs.

The Cry Me A River and former N*Sync star says his lifestyle is too busy nowadays to sit down at a piano and write songs.

"It slows me down," he explained. "I go into the studio and come up with an idea, then bounce it off of whoever I'm working with or if I'm by myself, sit down at the piano and start banging it out."
