What is the VERY BEST CD album you've ever heard?

For me it is Incubus / Science. Unique, interesting, recorded well and definitely rock.

I have to agree the Beatles in my opinion are a pop band, with one or two rock songs in their locker, all music is not Pop, it not all rooted in Rock n roll, pop is a mainstream popular music, a great deal of rock music is born from the blues, Metallica is not Pop they are a massive metal band but you wouldn’t define them as being popular with all listeners yet my favourite band, Jazz also is not Pop as it’s not popular across the board and I’ll vouch for that as I can listen to the stuff. 

You wouldn’t declare One Direction, Take That, Coldplay rock bands. 

To really hear and “show off” what my system can do it’s Diana Krall’s “The Girl in the Other Room”. Plus every single song is just so emotionally involving especially “Departure Bay” the last song on the CD. It’s honestly the one CD I play in it’s entirety and sit with my eyes shut and do not move…
 

For just pure jammin out it’s undoubtedly Iron Maiden “Live After Death”! 🤟🏻🤟🏻 Man that one is truly timeless!😂

@mrmeaner Once again, as we see in this thread here, someone made a fuss about calling the Beatles, “rock.” Who cares? We all know the Beatles. Nothing bad is going to happen, no egregious misappropriation occurs if someone calls the Beatles “rock,” or “pop,” or whatever. It’s all madeup label malarkey anyway. It’s all pop.  
Yes, everything in popular music is essentially rooted in Rock and Roll. I really don’t want to be didactic and don’t have the energy for a history lesson, but, yeah. Everything from the last 60+ years of popular music essentially flows from the Rock and Roll Big Bang of the mid-‘50s.

Metallica has sold 125 million albums.  
Nothing is “popular with all listeners.” 
You’ll actually find people that don’t like…Michael Jackson…Beatles…Adele…Mariah Carey.  
But Metallica has sold 125 million albums.  
Pretty popular. Intro, verse, chorus, repeat, bridge/interlude/solo, repeat.  
Pop. 
I already said Jazz and Classical wasn’t pop.  
I don’t know how I’d describe One Direction, Take That and Coldplay other than, “crap.”

One is free to call this stuff whatever they want.  
I just prefer to describe the sounds of things than to just bluntly, hamfistedly apply made-up marketing labels to music.  

People either are brainwashed by all the marketing labels and accept them as “fact” or “truth,” just really enjoy segregating and labeling things, reflexively equate “pop” with “bad,” or some combination of all the above.

I think of a couple of releases that seem to me be creatures of the CD era:

The Centennial edition of The Complete Robert Johnson brought out sounds I don't think anyone ever knew were there.

Though I don't know that it's any great shakes sonically, the 1988 studio cast recording of Show Boat was a revelatory document of what was possibly the greatest American musical.

Another monument of the CD is the encyclopedic box set: the Bear Family collections of Uncle Dave Macon, Louis Jordan and Bob Wills, the Bluebird Fats Waller and the Fremeaux Integrale Charles Trenet are particular prizes to me.

This rock vs. pop thing is obviously some sort of snobbery but I can't quite see what it's being snobbish about.
