Albums you do not get...a plea for help and understanding

Back in the Fall on 1977, I was in the back seat of a friend's car, getting a ride home from high school. The radio was playing and someone said, "Hey, this is Queen's new song. Turn it up!"

"We Will Rock You" was playing. Stomp, stomp, clap... stomp, stomp clap... along with Freddy Mercury, coming out of the 6x9 inch speakers, inches from the back of my head. Then the feedback of Brian May's guitar started coming through, building up to that first power chord, and that mean sounding guitar!. It was the first time I'd heard it and was quite simply, in awe. What is coming next here? How do you top that?

Then the opening lyrics of "We Are The Champions" started.

Total buzz kill! Literally! You're kidding me, right? One of my first anticlimactic experiences.

What am I missing?

Both kinds, Country and Western.

Brad Mehldau = zzzzzz. Kenny G = barf. 
Most screaming singer metal "music" = aargh.
Rap "music" = wtf? Most country music = yawn.
Post 461 Clapton studio albums = why? 

Post Who Are You? Who = again, why?
Paul McCartney solo albums after Ram = really?
et cetera...

I can’t understand anything by the Grateful Dead. And I really tried, even working at one of their concerts as security no less (UMaine April 1983). Worst concert ever. Never met a fan who wasn’t insufferable. Am I the only one who thinks they all sing off key?

As for a single specific album, Captain Beefheart and His Magic Band - Trout Mask Replica.  Rubbish. 

i never grokked Sun Ra, god bless him RIP. when i heard him sing "space is the place" i just stood there slack-mouthed in non-comprehension. i don't know what i was supposed to be hearing and enjoying.
