New You Can't Use

First off, there is a lyric from a song that goes something like:

"I don't get no sleep in a quiet room."

Ignore the obvious double negative and consider the following question:

Does he not get sleep because the room is too quiet?
Does he not sleep just in general, even if the room is quiet?

Also, is it fair to say that any performance appraisal a suicide bomber receives will be a poor one?

See, these are the things that keep me up at night.
