I've read a paper which had a similar theory - music is a reward hack for the brain - the brain is a prediction machine, and it gets rewarded when it correctly predicts stuff. Music is highly predictable due to it's rhythmic mathematical structure, thus very easy to predict, with a lot of content to predict (hundreds of events per minute) thus you get a lot of reward from it.
As an example, EDM music is highly predictable, and highly popular.
African tribal drum music is also highly predictable, while also being complex in poly-rhythmic ways.
