By composer (I'm a big score fan)
John Williams
-Schindler's List: probably the greatest score ever written. Very moving.
-Jurassic Park: the reason I picked up a trumpet in high school! Great themes.
-Star Wars Episode V: what started it all; great themes once again.
...
There are too many to list.
John Williams is brilliant. He has composed the most amazing scores... Also: check out "Summon the Heroes" and "Olympic Spirit". Wonderful trumpet work.
Hans Zimmer
-Gladiator: great rhythms, good use of female singers; borrowed themes from The Planets
-Power of One: amazing, powerful African-influenced music. A MUST. (see my thread)
Howard Shore
-Lord of the Rings: of course
Very dense orchestration, great themes; very evocative!
James Horner
-Braveheart: gotta love the bagpipes!
Horner tends to rip himself off; his Braveheart themes have been used (with slight variations) in numerous scores... But Braveheart remains a must-have.
