I've never been shy to confess my likings. In the early 70´s it was completely uncool for a prog-hippie to like the Sweet (and some other Chinn-Chapman-stuff), but I kept praising the quality of the vocals and the unsamed catchyness of the songs. My bandmates also laughed at me because I loved Ray Charles and Shirley Bassey.
And many Eurovision participants too (I liked, I mean, not that they laughed at me   )
 
But that Ding-dinge-dong.....c'moooon :o)

Yikes.  "Dancing Queen" is one of my own, but in all fairness to myself that last chorus is a perfect "wall of sound" on vinyl. 
 
I have guiltier pleasures though.  I can eloquently get through a 5 minute Archie's & Partridge Family musical conversation without blinking.   

You gotta see the film "Priscilla, Queen of the Desert" ... fun fun!!!
 
Hard to say ... but mine would probably be something like the Kinks ... I wanna be like ... david watts ... or a whole bunch of the that "Something Else" album. Other than that, one of my faves ... "Itchicoo Park", but their album "Ogden's Nut Gone Flakes" is still on my "top ten, if I had one. The Moody Blues "Days of future Passed" also is in that list.

Mine from '58

 
More recently than '58

Sorry. I tried to warn you guys but the spam killer killed my updated post.

Here's one I watch every now and then without telling anyone because it never fails to put a smile on my face.
