Oh, definitely!

As I said, just check out the score for "Transformers" for an example of Jablonsky, and try either "Bolt" or "The Bourne Identity" for Powell, although I've only listened to Transformers and Bolt myself.
Which also reminds me that I haven't heard too much of Hans Zimmer's stuff, either. I have the soundtrack AND the complete score for LK, and I have the Gladiator soundtrack as well, but does anyone know any other REALLY good ones from him? (that's probably a stupid question, really

since they're all good).
Here's what I've got and heard of his stuff.
-The Lion King (duh)
-Gladiator
-Call of Duty: Modern Warfare 2 (co-composed with Lorne Balfe)
Any recommendations of anything else he did to perfection?
