Philipp Lenssen has compiled a Sample List of Censored Domains in Google.cn (I made a few suggestions as to sources, hence I'm graciously noted). I think there's something interesting in this data, but it would require substantial time to try to analyze it.
Some of the sites listed are free web hosting services (like Geocities or Angelfire), others are international news sites or human rights sites. With these it's kind of obvious why the Chinese gov't treats them as opponents. For other sites however, like those of music bands, I didn't see any obvious connection.
Sharing the same IP? (Virtual Hosting). Domain inheritance? Copyright list traps? Somebody in the censorship bureau hates the music band? The mind of a censor can be inscrutable.
Update: For some different but related info, see Nart Villeneuve on Keywords & Google.cn
