Tool - Lost Keys->Rosetta Stoned
cKy - 96 Quite bitter beings->Escape from hellview
Pink Floyd - Anything by them
The Game - All I need OR Method Man - 4:20
A Silver Mount Zion - Anything by them
The Chemical Brothers - Elektrobank (But they have a LOT of good smoking songs)

And many more. I know it's more than 5.. Oh well. And the Tool/cKy songs gotta be listened to in pairs, such as lost keys/rosetta stoned.
