I consider music a weak point of the series. It's not that the quality is bad, but that everything sounds less Thedas and more Hollywood fantasy movie.
songs like qunari rising, too me were something that you wouldn't hear hollywod or in many other games. there is something fresh and very primal about it. while yes the music is somewhat "not quite there" yet, it isn't bad either. if thedas is like medieval europe, then the music would be very controlled and simplish. mostly with stringed instruments and grandparents to today's brass instruments.
by controlled i mean that the papacy pretty much wrote the rules on what music could sound like, the folk singers ignored them thankfully, but the pieces that were formally written followed notations approved by the church.
the music of the dragon age games to me, outside of the hollywood required themes, sound almost like a backlash to the controlled simple notations of europe circa 1200 ad.
that being said, i can listen to dark fantasy, and hawke's family themes all day long.
