Someone on Facebook linked to this audio file of a Justin Bieber song going 800% slower. It's hypnotic and kind of amazing. I posted it on Facebook with the comment--
"This 35 minute Justin Bieber 'piece' is the absolute perfect thing to play when my neighbor turns on her idiotic dance music. Sounds like a beach in a church."
-- and then started playing it for my friend when he came over. And as soon as we turned it off, we heard this weird echo of the music we'd just been listening to. "Is it still on?" my friend said. No... then we realized it was coming from next door--my neighbor was playing it too.
