Something for Everyone in Super High Fidelity

Like a missionary in the jungle, I continue to practice my usual high end evangelism with non audiophile friends, rarely finding the eager disciple.

Despite warnings of this peculiar audiophile habit in many other threads, I must admit I am often tempted to play something that sounds good, only to be reminded that music which people don't like (not to mention straight percussion or steam trains) probably wont inspire them to upgrade their stereo system.

On the other hand, we all know that deferring to a friends musical taste for a demo will immediately locate the screechiest, worst sounding recording in your collection.

Bearing this in mind (and maybe some of you have already done this) 1) what COLLECTION of well recorded tracks, 2) across genres of music, would you 3) put on a compliation CD or "rip" into WAV files to accomodate the widest musical tastes of future audiophiles?

Some classical? Jazz? Rock? Soundtracks?

Each of these genres have been discussed in other threads, but what tracks would you include to capture the widest possible audience as an audio missionary?

Thanks for ideas.
