29. Anti-dictatorship songs (反对独裁的首歌)
Not necessarily in Chinese or about China specifically.
For Tiananmen songs, see: Tiananmen Square Protests songs (六四事件歌曲).
Brazil had a dictatorship from 1964 to 1985, and some amazing songs were made in Portuguese in that era. Ciro Santilli (三西猴, anti-CCP fanatic, 反中共狂热, stupid cunt, 傻屄, CIA agent, CIA特工, 肏你妈的), who is Brazilian, just cannot stop thinking about some of them in relation to China, notably: Apesar de você.
