I need an opinion on noisy neighbors?

I would like an opinion on this incident. My husband and two young sons live in a duplex type apartment. Our living room wall is connected to someone else. In my personal opinion it is disrespectful to blast music when you're attached to another person's home. They blast their music so loud that we have to blast our tv to hear it..and they have surround sound which doesn't make it any better. I have a 2 year old and a six month old and I feel horrible turning the tv up so loud that my 2 year old can barely hear me when I call his name. And if they're sleeping/napping obviously I can't turn the tv up. I have been extremely nice about this until recently I finally got fed up with it and called the cops so they would know that we are serious and it is really disruptive to us. I didn't call the cops to try and get them in any serious trouble or arrested I just wanted to get my point across. I had tried several times before this to talk to them and they would act nice to my face of course but it would still continue on later. These people are late 20's and parents. The mother I guess finally worked up the nerve 2 weeks after the fact to come over and ask me about it. Not apologize but just to tell me that it was extreme and that she was a "social butterfly" and she "didn't feel like she could be herself because she had to worry about upsetting us." I tried reasoning with her and explaining that we can't enjoy an evening to ourselves to watch a movie that night because of them. She asked me if I could just "endear" it because it was only one night! I told her no and that I will not be uncomfortable in my own home just so they can blast music. We have never done or will ever do anything to disrespect them so is this such a huge request to ask of someone?
