Okay, since I apperently overdosed on the sarcasm again, I'll try saying it plain and simple (just like The E already did, though I'll elaborate a bit more):
Those songs do not fit in at all with the current soundtrack and quite frankly I don't think they fit into the whole setting and atmosphere of Wings of Dawn.
WoD is mostly "happy go lucky" with a bit of a darker and mysterious streak at times (which makes the occasional orchestral or choir piece fit in nicely).
But those hard core metal songs invoke very different emotions in me (not to mention nervous twitching).
With this I'm refering only to the metal songs you posted. The Cardassian theme from STO might be a nice addition to WoD.
