I would say that Scorsese's best go like this:

1 GoodFellas
2 Raging Bull
3 Taxi Driver
4 Casino
5 Cape Fear

(I haven't seen Mean Streets but I've heard it's damn good).

Glad you liked Casino, I loved The House Of The Rising Sun song, I agree, could'nt be a better music choice.

Only after the last tree has been cut down
Only after the last river has been poisioned
Only after the last fish has been caught

Then you will find that money cannot be eaten.
