You don't say what YOU like to listen to, but here's a few suggestions that don't drive me crazy if I play them when my wife is around:
Any of the Mark Knopfler soundtracks, "Cal", "Local Hero", "The Princess Bride", etc.
Any album by Sting that has "Englishman In New York" on it. :-)
The Clannad albums "Magical Ring" and "Legend"
Dave Grusin's "Cinemagic" - a great album!
Mark Knopfler/Chet Atkins "Neck & Neck"
Knopfler & The Notting Hillbillies "Missing, Presumed Having A Good Time"
Any of the three Linda Ronstadt albums with Nelson Riddle - "Lush Life" What's New" or "For Sentimental Reasons"
Any of the "MTV Unplugged" albums by Eric Clapton, Paul McCartney, Neil Young, Sting, or Paul Simon
Rani Arbo & Daisey Mahem "Cocktail Swing"
Eddie From Ohio "Quick"
Jackson Browne "Solo Acoustic-vol. 1"
Bruce Cockburn "Speechless"
Also, a suggestion. If you are an older gent, and have tone controls in your system, and have the treble turned up - turn it down to flat. Women retain their high-frequency hearing much longer than men, and a too bright system may be making her ears bleed, while it sounds fine to you. That's a common problem area with men & women & hi-fi systems.
I hope some of thsi helps,
Ed
