Why people don't like new music.

From The Composer's Datebook

[2/4/]1837 - Franz Liszt performs a chamber recital in Paris, featuring the then-unfamiliar Piano Trios of Beethoven; At the last minute, the performers decided to reverse the printed order of the program, performing on the first half of the concert a trio by Pixis, and a Beethoven trio on the second half; The audience (and critics) warmly applaud the Pixis, mistakenly thinking it was the Beethoven work, and react coolly to the Beethoven, assuming it was by Pixis; Among the critics, only Berlioz notices the program switch.
