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

Fitting category of pop band to Beatles is simple because they are pop somewhere above 90% of their career. We can call it pop-rock as well that will match even better.

There are bands that very hard to fit into any category, but the're obscure and rare and definitely not Beatles or any RR hall of fame artists. 

Maybe good example of Goz of Kermeur. Their self-titled album I think is third on my list.

Beatles isn't a rock band. It's pure pop. Calling it rock is delusional.

@bigtwin DEFINITELY Jimmy Smith/Harvey Mason supposed to be bombastic!

all-right.

Let's call the common stuff mainstream whether it's rock or pop or hop of any kind.

Mainstream usually can be found in thrift stores for less than a buck
