Radical Notion is the fourth track on the album Inception: Music from the Motion Picture. It runs for 3:43 minutes. The title is a reference to what the old Saito said when he talked to Cobb in Limbo.

Saito: You remind me of someone... a man I met in a half-remembered dream. He was possessed of some radical notions.

This played when Cobb was sharing his second dream with Ariadne and she is stabbed by Mal at the end.
