I see that you took that disco image on the twitter page to heart.
It's a little bit difficult to understand at first; it's rather dark and the brown square that indicates a line array doesn't stand out at first; perhaps an indicator of sorts would help. It also took a little bit to learn how to play songs, since the when I clicked on an active line array the first song it showed me on the menu required more trophies than I had; perhaps starting the list on a piece that requires 0 trophies would be better. The most important problem is that it's hard to tell what your police and the criminals are feeling. For an extreme example of what would probably be more obvious, you could color people green if they are happy with the music, and color them more red the less they like the music. Green policemen would break the immersion quite a bit though, so try something else to make it obvious. It is difficult to judge the mood based on masses of overlapping clouds.
In general, communication seems to be the main problem, though you didn't mess it up that much either. For example, you added indicators for the line array radii, so I could tell who was being affected by my music. Music tolerations also helped a lot in my decision making. Small note: you can't click on police behind buildings to check their tolerations. Overall a nice game.
