I suppose some things are called guilty pleasures because one is appparently embarrassed to admit liking it. Maybe some feel their credibility might be called into question for liking something not hip or cool or too old-fashioned.
Reading the fascinating and entertaining book, Shock And Awe, by Simon Reynolds has caused me to ponder the musical recordings that I've often called my guilty pleasures. The book is subtitled, Glam Rock and Its Legacy, from the Seventies to the Twenty-First Century. It looks at music which became know as glam-rock from a very British point of view. It features chapters delving into the music of Marc Bolan and T. Rex, David Bowie, Alice Cooper, Slade, The Sweet, Mud, Suzi Quatro, and Gary Glitter as well as the New York music scene which produced the New York Dolls. It also reviews a number of British artists not so well known in the states.
Growing up in the home of a couple of transplanted Texans, one a first generation Mexican-American and the other one an East Texas hillbilly, we were exposed to a wide variety of music. Everything from Gilbert and Sullivan to Hank Williams could be heard in our house. Show tunes and big band crooners competed for listening time with Tennessee Ernie Ford and Patsy Cline. All four of us children were required to take music lessons. Our oldest sister opted for the violin while I with my two younger sisters took piano lessons. When rock'n'roll infiltrated our home via television and radio I began to learn to play guitar.
Having been raised Roman Catholic pre-Vatican II I'd been exposed to really good liturgical music. In the men and boys choir we sang Bach and Mozart and even Gregorian Chant.
I will listen to and enjoy anything that tickles my musical fancy and not pay much attention to which genre it occupies. Even after thirty-plus years of marriage Mrs. Metal Dad cannot fathom my fondness for music from Anthony Braxton and Albert Ayler. #1 Son has raised an eyebrow on more than one occasion when something like Roxy Music or the Carpenters was emanating from the car's CD player. My listening usually falls along hardcore or metal lines but I will listen to anything.
I just like what I like and don't feel the need to justify it to anyone.
