I vote kill them with kindness...if that doesn't work...

I had this same problem with a neighbor once...she liked to play John Denver REALLY loud, and then sing along REALLY loud. Well she lived in the apartment above us, and we had one of those dropped ceiling things. We took the tile things out of the ceiling and put all of the speakers in the ceiling and played our music (I think it was marillyn manson?) loud enough that it didn't annoy us, but we were sure it would annoy her (except when we left the house and turned it up ) 24 HOURS A DAY!!...it worked, after about a week she came down begging us to make it stop, and we never heard John Denver (or her horrible singing) again.
boys lie.

No we do not!!!!
