Awww sis :( Well if it was that loud then I don't blame you!
We used to that a similar problem with our former neighbour, I don't know how he could bear to be in his flat as you could hear it through the wall, bedroom wall, lounge wall in the lounge!
I was having a grumpy moment on a bus the other night with some yoof sat behind me one side with his "noise" (hold old do I feel saying that!) blaring and the side side had some of the local youth offenders effing and blinding and going on about what they'd been done for....argh!
