Oh yeah, those dance moves are quite something ;)

lux aeturna- Clint Manswell
its a bit slow at the beginning but gets pretty dramatic

This one always gives me chills for some reason. And I hated that book with a passion.

To answer the question, Arcade Fire. Notably this one:

Anything by Van der Graaf Generator, and I do mean anything.

A dramatic film deserves a dramatic song.

Lisa Gerrads "Now we are free". Just pure magic.



Enya's "May it be". Perfect.



edited for this addition.

Part 1(albeit this is way to quietly recorded):



Part 2:

The Prophet's Song by Queen, absolutely.

One that comes to mind is The Musical Box by Genesis. They were infamous for there long drawn out songs in early Genesis and put on quiet a live show. This to me is one of there more dramatic songs.

Bacharach songs often, quite a few Italian songs, some Korean, Vietnamese music can be quite dramatic, operatic music can be.
