Cover art for Come Undone lyrics by Robbie Williams

This song is really obvious, I'm amazed by people missing the point.

This song is purely about Robbie and stardom - and him being a creation of the media and the fans etc. They make him famous, they create the cycle, he just lives it.

Selling razor blades and mirrors is obviously a cocaine reference, but it's a metaphor for a bigger picture. Again, he's saying that they make him what he is - they write the stories, they provide the tools, the fame and the wealth. He is a product of the environment created by the media and fans - who then are the ones who judge the stars for what they become.
