My neighbor is doing some intense work around the house involving drilling/hacking into concrete (I think).

I work from home so I looked through the SomaFM list of stations and picked out the dubstep one to drown it out. I never listen to dubstep.

I realized in between songs that the sound of the concrete drilling was indistinguishable from the music; it was only then that I realized it wasn't actually from my headphones.
