Query: Guaranteed to make a Scrooge out of you

In recent years I've found myself growing unaccountably grouchy as Christmas approaches. Finally, I figured out the problem: my wife played this CD. The Roches have only one volume, loud. They make no effort to blend their voices. They don't always stay on key. They don't try to capture the spirit of any of their songs, singing everything in the same top-of-the-lungs way. Listening to this CD is like nothing so much as being in attendance during the third hour of a kid's birthday party, when the kids are hitting the wall with sugar and fatigue and the screams grow out of control.
