(-)! That's annoying, I recognise ALL of those songs. That means I must own whatever game they're from, and had them on my computer.
The names of the files rang a bell, and after doing some Googling I realised the most obvious answer - they're from Shogun: Total War. Which makes sense the song would be so recognizable to me, I used to play that game hours upon hours.

Thanks btw
It kept me awake all night trying to remember the song.
