The most frequently asked question I have gotten so far is if there are genres where emotional resonance doesn't affect listeners enjoyment of music? 

A: The most common example given for music that isn't emotional is experimental and avant garde music. Obviously John Cage's work of "4'33" is hard to find emotion in, but even that emotion is a sort of an engagement. There is obviously some music made to just provoke thought and where that is what's most important. Same with noise music or drone where you are using the music to designate a time to meditate on a thought inspired by the tone you hear. 

With that said there is no genre where I see anyone who makes unemotional music that is enjoyed by a great deal of people. If you happen to find one, please alert me to it.
