I agree with the sentiments written by @millercarbon and others: let the listener choose. If a music selection is not increasing brain [dopamine], your guest will not enjoy the listening session. Worse yet, if they actually dislike the music playing, they will find an excuse to leave the room and quietly, or openly, question the wisdom behind your expensive hobby! If it was just about the sound quality, I wish I could play, “The Power And The Majesty” recording of the steam train! I heard it once, over 40 years ago, at an audio store in Richmond, VA. Have a great day!
What selections do you play when showing off your system to others?
I find that when I'm having someone listen to my system that I usually play the same 4 or 5 selections. I tend to lean towards vocals and acoustic presentations. Mine are as follows:
Hold That Line- Tedeschi Trucks Band
Roadhouse and Automobiles- Chris Jones
The Hunter- Jennifer Warnes
River Blues- Eric Bibb
Flight of the Hippo- Bela Fleck and the Flecktones
It's All in the Game- Merle Haggard
Your Bright Baby Blues- Jackson Browne
What are yours?
