According to a BBC report (see link below), Beijing pointed figures at "China Democracy", a new album from Guns N' Roses, and dismissed it as "venomous". In July, Beijing ordered that any foreign entertainers threatening "national sovereignty" would be banned from the country.
Foreign Ministry spokesman Qin Gang told the BBC's James Reynolds: "According to my knowledge, a lot of people don't like this kind of music because it's too noisy and too loud." Fair enough, why not also ban the loud Chinese rock music and the noisy revolutionary songs?
Let us be creative here: what else can you do to be banned or put on a blacklist? :-)
