For the most part, the loud music happens during the summer months from May until August... I don't know what street you live on, but we built our house back in 2006 and when the home behind ours was finally built, they moved in and it was a constant party. After 11pm we started calling in noise disturbances to the police. After the 6th time or so, they stopped having loud parties. I suggest trying to get to know the noisy neighbor and getting on their good side. After a while you can mention that their music is exceedingly loud and disturbs your family. There's no reason for music to be that loud. We've lived here since most of the neighborhood wasn't even built... and have had no real problems besides occasional graphiti and one of our cars was rummaged through one time (but the door was unlocked so that was partly our fault.) And again that happened inthe summer when teenagers get bored. Since then no problems, knock on wood. I hope that the neighbors have calmed down since you posted in May. Good luck.
