I guess mine would have to be: Carole King, Joan Baez, Joni Mitchell, Peter Paul and Mary, Judy Collins, Roberta Flack. Ummm... do I have to turn in my man card? Not to many who cared to hear those in High School or at Old Frat House. (They also didn't like Springsteen, I did).
And as much as I really didn't care to go to Disco's, not all Disco music was that bad. Some is even good.
But in my opinion a true guilty pleasure is one you are really almost ashamed to admit you like, you will deny it...
Well the Bee-Gees would be mine, including the Saturday Night Fever sound track.
My next one is there are a few songs by The Carpenter(s) I like. A few by John Denver.
But my biggest embarrassment ever was: I promised to take my wife to a Barry Manilow concert for her birthday. An out of town business meeting was called for that date; I had to back out of attending in person and participate remotely and tell everyone why I couldn't go. Truth is I also liked some of Manilow's tunes, too.
