It's too hard for me to put them in any order, but these are my all-time favorite albums that I can listen to over and over again. A lot of them are popular choices and mights seem obvious so criticize me all you want, haha.
* Pink Floyd - Dark Side of the Moon
* The Beatles - Sgt Pepper's Lonely Hearts Club Band
* The Velvet Underground - Loaded
* Chicago Transit Authority - Chicago Transit Authority
* Simon & Garfunkel - Bridge Over Troubled Water
* The Moody Blues - To Our Children's Children
* My Bloody Valentine - Loveless
* Radiohead - OK Computer
* Ride - Nowhere
* Smashing Pumpkins - Mellon Collie & the Infinite Sadness
* Oasis - Definitely Maybe
I've got more but those are what came immediately to mind xD
@AgeofOddz out what you picked I really like The Cure, Sonic Youth, The Doors, and Joy Division ones in particular. Good choices
