Okay, nearly all of these can't really count as a "classic" but anyway... In no particular order:

Massive Attack - Mezzanine
Red Hot Chili Peppers - Californication
Air - Moon Safari
Radiohead - OK Computer
Morcheeba - Who Can You Trust
Morcheeba - Big Calm
The Cranberries - Wake Up And Smell The Coffee
The Cardigans - Gran Turismo
Portishead - Dummy
Placebo - Without You I'm Nothing

I did have "Simon and Garfunkel - The Definitive Simon and Garfunkel" at the end but since I'm not allowed greatest hits albums I've replaced it
