Music from 2A

(This was in the Blog Mailbox this morning - )
Just wondering if anyone else hears the constant music they play in 2A. I know I hear their band practice and so do the neighbors above me (the elevator shaft that runs through the A apartments lets noise travel freely) that goes on well after 9pm on weeknights. I know I've asked them to stop, and tonight I heard someone yell for them to stop playing piano, but then they just went into their room and started play music with lots of bass at 12:10am on a Tuesday! This is a common occurrence, too. Last Monday night, they were playing bass-heavy music in their room from 12:30am - 2:30 am despite my going down there to knock on the door. I always have to resort to stomping on the floor multiple times before they get it. Do the guys in 2A disturb anyone else?

Is anyone else having water problems?
