There are a few good 'complete' soundtracks but a lot of great songs in the disney arsenal. Because of that, I'm thinking of putting together a compilation CD, or three, from the tunes I own.)
But, to answer the question, I'd have to go with:
a) Mary Poppins
b) The Jungle Book
c) The Nightmare Before Christmas
d) The Lion King
e) Beauty and the Beast
f) Aladdin
g) The Little Mermaid
