I'm look for a good, exiciting,fast-paced possibly fantasy-like soundtrack from itunes! Does anybody have any ideas? I mean like a orcestral soundrack please...

I'm a huge film score buff! below are my suggestions, they are all fantastic.

~The Island- Steve Jablonsky
~The Fountain-Clint Mansell
~Stardust-IIan Eshkeri
~Children Of Dune-Bryan Tyler
~Edward Scissorhands-Danny Elfman
~Pirates Of The Caribbean: Curse Of The Black Pearl- Klaus Badelt
~Saw soundtracks-Charlie Clouser *not quite a Fantasy but the theme is fantastic and can be heard in the first 3 film soundtracks.
~Requiem For A Dream-Clint Mansell** this is used quite often in other movie trailers especially the 'Lux Aeterna' remix.
~Chronicles Of Narnia (both soundtracks)-Harry Gregson Williams.
