These aren't albums I'd consider to be "Best ever". Just my favorites.

1.

Dookie - Green Day

Standout Tracks:
Burnout
Longview
Welcome To Paradise
Basket Case
When I Come Around
F.O.D

Welcome To Paradise - Green Day

2.

Make Yourself - Incubus

Standout Tracks:
Privilege
Nowhere Fast
The Warmth
Stellar
Make Yourself
Drive
Pardon Me

Pardon Me - Incubus

I could do more, but it'd just be more Green Day/Incubus albums.
