Evangelical Denos in the War Against MP3

There are several great threads on recommended music, but here is a slightly more challenging twist:

If you only had ONE TRACK to convince a NON AUDIOPHILE why they, too, should rush out and buy a stereo that cost more then their BMW, what would you play?

Ideally, you might even give your audience a choice: pop, jazz, classical, rock and roll etc. but in my opinion, subject to the following rules:

1) nothing too esoteric -- geeked out hi fi demos dont impress laymen!

2) Enough variety to allow a choice -- "You may not listen to jazz, but this obscure recording by Flim and the BBs blah blah blah" does not inspire people to abandon their Bose Wave radios.

3) the recording must be impressive but non fatiguing at a reasonably dynamic volume sufficient to demonstrate your big rig

3) in addition to an impressive demo, what music AND perfomances have passed the test of time, could rightfully be considered "classics" and could move you emotionally even through a lesser system

I know this is not easy, but some great ideas will give us all the last demo track list that we need.
