Cover art for Citizen Erased lyrics by Muse

It says on the Muse Wiki that the song is about Matt's constantly being asked questions about his purpose, and his struggle with having to answer these questions. He feels that, after these things are put into print, he's already changed his mind and there is no way he can really explain or describe to people how he feels about his work. After reviewing the lyrics, I really feel that this is what the song is about, at least in some aspects. The lyrics seem to suggest that he feels trapped, forced to fit into people's ideals of who he should be.

But then. Maybe not.
