How exactly do you install this mod for Rome Total War: BI?

I installed the mod from here:

https://forums.totalwar.org/vb/showthread.php?t=84124

There are a few files here.

Music_for_OIM.p
Music_for_Oim.p
eng.exe
OiM_lit_eng.exe
patch_music_for


Can anyone please tell me how to install it? Do I extract all of the files into my BI main folder?
