Jogs post above illustrates my earlier point about the english lyrics... It was enjoyable through all the bits that this lady was not singing. And I'm not saying that her singing is bad. It certainly is way better than Mallukah. Instrumental music works to enhace our own perception of the world in our imaginations but when you add in lyrics it immediately becomes a spesific story. It cages the imagination to a predefined path and mostly breaks immersion for me. Lyrics that one cannot understand are a different deal. They cannot cage the imagination as such because words that you dont understand are just undefined sounds like an instrument.
I am also wondering wether Darth Trethon has any idea what musical cohesion and atmosphere in a work of art, such as this game, means... Every genre of music ofcourse can have it's place, but you cannot just suddenly drop a completely different style of music (dubstep in this case) in the mix without it feeling out of place. (AND we know from the pieces already provided, that this games soundtrack is not going to be dubstep.)
