I'm not worried about which song you select, (Notorious KKK is the ideal choice, obviously) I'm just worried about you not getting in trouble for this. Make sure that the speaker can not be traced back to you in any way. Wipe it clean of fingerprints, put the music on a delay from the time you placed the speaker, and make sure no one sees you fucking with the Moonman statue. Also, make sure the video can't get you in trouble either. Make sure that no one notices you recording it, and that your face isn't in it.
You could get in really deep shit for this, so be smart. Also, we need to see that video, and we can't if your phone gets confiscated and you get thrown in jail! Make sure the video has good shots of children saying stuff like, "Mommy, what music is that?" and parents frantically trying to cover their ears.
Godspeed, moon! May you succeed in your righteous quest!
