So this is the second half of the thread 'Guilty Pleasures'...Well, my wife likes to listen to half of whats listed on that thread, and I didnt realize some of it was embarrassing, so...
My family adapts to most of what I play from reggae to bluegrass to jazz to country to rock to just wierd.
I can take the Carpenters but I usually leave when she plays Barbara Streisand. Ouch! Sorry.
I will spare my wife heavy stuff like King Crimson 'Larks Tounges in Aspec' or Praxis 'Transmutation', maybe very old Zappa....not that much she cant take. She seems to enjoy 'Yoshimi Battles the Pink Robots' by Flaming Lips, but probably not as much as I do. I enjoy playing the Dean Martin albums her mother left her. My kids never seem to be saying "I hate that music".
Maybe I have it easy, I think we are blissfully ignorant of embarrassment.
...Ok, I came up with one thats only appropriate for close friends or for weeding out the hardcores at the later stages of a party : Poor Dumb Bastards, I think out of Houston. Wonderfully offensive, unfit for any audience. Any Bastards fans out there? Expose yourself now.
