FUCK!
I just found out that the new neighbors upstairs have a band, and are planning on practicing twice a week. I'm now in the position of being the bitch downstairs complaining about the noise.
Agro time. Give hell ANYTIME they start playing to the point that you're routine is being interfered with. Follow up with multiple phone calls to the landlord/property management agency and document with a pad by your phone (date, time, duration). Better yet, figure out a way to attach your phone to the wall from where the sound's coming through and call the landlord's answering machine. Let the music be your message to him/her.
You might then follow up by filling a used cereal box full of Texas fire ants. Fold the box opening into a nice crease that'll fit under the crack of the neighbor's front door and let the critters crawl into their new home. You might also consider buying a pair of small, efficient stereo speakers that are about the size of a half pint of milk. Put Diamanda Galla's
Plague Mass on full volume and make sure you set your CD player on 'repeat.' Then take off for the weekend.
Hope that helps.
