This story about drill rap music raises an interesting question of the psychological effects of different kinds of music. My general impression is that the DJ’s at the Argentine tango milongas seem to prefer high energy music at loud volumes which seems to stimulate activity and competitiveness. The ambience is generally not very relaxing. If the attendees have the habit of listening to pop and rock then perhaps they also prefer these selections, but perhaps a habit of listening to classical music might temper their musical tastes in a more constructive direction. I recommend J. S. Bach and Frederick Chopin, and even piano performances of Astor Piazzolla can be good as well.
