Sorry to come late to the fray (as it were), but viz. the medieval music may I suggest Medieval Steel? The latest research suggests that this is what the French knights listened to before they went off at Crécy, Poitiers and Agincourt. Whether it made them frenzied or suicidal is not certain, but effect was that they rode breakneck for the English lines.

For those who cannot stomach sitting through such unadulterated manliness, may I suggest skipping to 4:09, a moment that cuts straight to the very essence of what this song is about (that is, leather and very tight codpieces).
