Put on "Jazz Impressions of Japan" during a desolate looking section of a long highway drive. She probably wouldn't boot you out of the car for that?
Our common ground in music is 50s & 60s oldies. The only Brubeck tune she will tolerate is Take 5. I have 30 versions of Take 5, ranging from 3 to over 16 minutes. I once burned an 80 minute CD of my favorite versions for a trip. By the end of the second one, she realized what I had done and ejected the CD.
