Listening to this record can cause changes in internal hearing system, so it's considered as dangerous. Title of album is: "Mroczni Bracia Grom i znajomi - Harry Potier zginou! Buahahahaha. I zabił go Gandalf :P:P:P"; it can be translated as: "Gloomy Brotherhood of Thunder and Friends - Harry Potter is dead! Buahahahaha. And Gandalf has killed him."
