No charge on content....No Problem...but stick it to him heavily for noise pollution and nuisance charges. Fine equal to the caliber of his sound equipment and decibels. Very loud sound equals VERY BIG FINE! ....and if he does it again, an even bigger fine. He's not psychotic he knows exactly what he is doing. First round in Court his attorney did not argue any part of his charges due to mental illness, so the door is open, he can be prosecuted for his nuisance behavior no excuses....and even sued for causing neighbors stress and anxiety...a class action suit might be an idea to look into.  Like the near golden rule says....choose the behavior, choose the consequence. The cynical part of me kind of hopes he's a slow learner and does it again getting an even bigger fine. Springfield can put the money to good use.
