Great Music to Intro Non-Audiophiles to the Hobby

If you're just looking for something they might like to choose from (although you don't mention about how old they are) I can think of a slew of recordings on CD mostly from the 70's ('cause I'm an old fogey).

Goodbye Yellow Brick Road (Deluxe Edition, usually any of the DSD remasters sound good...usually)

Hot Rocks (DSD)

Al Dimeloa's Elegant Gypsy (a bunch of different remasters, most all of them good)

I Robot from Alan Parsons

Dog and Butterfly and Little Queen from Heart

Cassandra Wilson's New Moon Daughter

Romantic Warrior by Return To Forever

Frampton Comes Alive (25th Aniv, DeLuxe Edition)

Al Stewart, Year of the Cat

461 Ocean Blv and Slowhand for Eric Clapton

Let It Roll, George Harrison

The Love Album, The Beatles

Glass Houses, Billy Joel

Marsallis and Clapton Play the Blues (2011)

Late for the Sky by Jackson Bowne if they enjoy meloncoly love lyrics which would win an award for poetry.

The Pink Floyd sound much better from the vinyl than from the CD imo.
I would suggest the inevitable Patricia Barber and some Cassandra Wilson's albums like: Blue light 'til dawn, Traveling Miles, Thunderbird, Glamoured...

In case if you want to impress gay you should spin some Abba or Be gees tracks.

Here is a handful of my favorite CD's that I use for pleasure and for doing reviews:

Ingrid Michaelson: Everybody

Hugh Laurie: Let Them Talk (If, like me you don't mind Laurie's vocals it's some great well-recorded music)

Rodrigo y Gabriela: 11:11

Jack Johnson: En Concert (taken from his many live concerts)

Regina Spektor: What we Saw from the Cheap Seats (nice pop music... good piano, arrangements, and Regina's cute & dramatic vocals)
