antimusic

anti- +‎ music

antimusic (usually uncountable, plural antimusics)

   • 2015, Samuel Cameron, Music in the Marketplace: A Social Economics Approach, page 2:

     […] the current vogue, on the internet, for creating “black midi” files using software to create musical performances with literally millions of notes being played […] is unlikely to appeal to the general listener and we should probably consider it a deviant case of anti-music made for frivolous purposes rather than any kind of polemic.

antimusic (not comparable)

1. Opposing music.

     In other words, the lack of musical ritual in Canada cannot be understood as yet another case of Muslim antimusic sentiment.
