U2 - Joshua Tree (1987). "Without or Without You" (track #1) to benchmark the Bass.
Fleetwood Mac - Rumors (1977). #1 selling album of all time until Thriller (1982).
Pink Floyd - Dark side of the moon (1973). Amazing collection of sounds including a black hole, recorded at Abbey Road! If you don’t take drugs this may encourage you to start!
The latter two are still among the top-10 selling albums of all time with 30m+ sales!

I don’t really listen to classical but as a substitute I’d pick some art rock albums from Genesis or Phil Collins after he sold out. Did you know that Phil Collins is like the #2 or #3 selling pop artist of all time with over 130m album sales?
Genesis - Duke (1980). Their Opus during the art-rock stage.
Genesis - Turn it on Again (1999). Their Greatest hits from their Pop period but a few art-rock songs still like Abacab ...
Simon & Garfunkel - Greatest Hits (1972). What can I say their songs are still being used on sound tracks 50 (!) years later (The Orville 2022 episode "Domino") and they are the #1 folk group of all time! For #2, Peter Paul & Mary.
Dire Straits - Money for Nothing (1988). This greatest hits album is titled by the song "Money for Nothing", which is a frequent benchmark for dynamic range in turntable systems. This has one of the very greatest lead-ins of any song of all time. I don’t often listen to Dire Straits, but when I do, so do the neighbors!
Dave Brubeck - Greatest Hits (1966). If you aren't into Jazz Yet, this will GET YOU IN and it will truly exercise your turnable like nothing else!
