Dystopian classical music will be a short-lived fusion of rap music and classical music. It will be conceived in the year 2015 in a vain attempt to attract more adolescents who were born after 1996 to classical music.
Eminem's daughter will be one of the first artists in this genre (that would later be considered the Edsel of the music world). Lyrics with vulgar language are constrasted and mixed with those of violins, cellos, and grand pianos. Dystopian classical music will never gain the broad audience spectrum that world beat music can and will finally die as a genre either in or around the year 2032.
Winamp or something similar will also be used to play both Beethoven's 5th and Snoop Dogg's "Ain't Nothin' but a G Thang" at the same time. People rapping to violins with pre-recorded music is a sub-genre of dystopian classical music.
However, the traditional form of classical music will have a total monopoly on the known universe by the year 2498. All other forms of music (including rock music, pop music, rap music, and even world beat music) will become obscure and people will listen to Beethoven instead of 1970s disco tunes.
