A couple of Russian dudes back in the 90s took a poll of the types of music people despise the most: bossanova(?), "oompah-ing tubas", Wal-Mart (wtf?), and George Stephanopoulos (ah ok) - among others. They then compiled all of these monstrosities into a 23 min. song. Listen for the opera rapping about a minute and a half in.
