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

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. 

The biggest gateway for me was Michael Franks. I was mid twenties staying in a cabin on Lake Tahoe doing research (I was a geologist). I went to this tucked away high end cool restaurants hidden in an old growth forest. One of his albums was playing… it completely changed my world… opened it up.

Prett much all his albums are good too!

Zappa. Just don't get it. 

Purple rain. Spun it recently and didn't make it through the first side.

Laurie Anderson. Want to understand, I just don't
