Hello~ I've been searching for the best kind of orchestrated (or at least what sounds like orchestrated) music, and I was wondering if the people here could help out.

I'm looking mostly for action/medieval music like Unwavering Resolve (http://www.youtube.com/watch?v=Ed2XtMSaYUs) from the Soul Calibur series or Leap the Precipice (http://www.youtube.com/watch?v=dhMBb2mtc3s) from Eternal Sonata.

Or if not that, then even calming music, such as this song here (http://www.youtube.com/watch?v=43e8pEm0Un8).

If possible, can you recommend me such music? Thanks in advance!

Video game and anime soundtracks work well for what you're looking for. Just buy them (or download) and you should be good.

Have you checked out the Big Orchestral Action Music Thread (Thread 57893)? There's an absolute wealth of stuff there. Everything from game music to anime, film scores to classical. :)
