Already lots of LOTR & Tron: Legacy here. Not seeing much love for animated film scores, so on that note & in no particular order:

• How to Train Your Dragon trilogy, 1 is personal favorite
• Kung Fu Panda trilogy, 2 is so fucking good oh my god personal favorite
• The Lion King (1994)
• Spirited Away
• My Neighbor Totoro
• Spirit: Stallion of the Cimarron
• The Super Mario Movie
• Finding Nemo
• Up

A couple of these have great soundtracks, too, but I do love a good score.
