To get the music into the game you just have to open the zip folder and copy paste all the mp3 files in it into your Victoria 2 Music folder
I made this mod(?) or more like collection of Ottoman songs which fit into the period of this Empire between the late 18th and early 20th century to get more immersion into my playthrough because whats more epic than going into war with Ottoman military marches?
Also I did not only add war songs but a variety of songs and marches from traditional relaxing Ottoman songs to more Western styled onces . The most epic thing about it is that many of these songs I used were composed by the Sultans itself like Mahmud II. , Selim III. , Abdülmecid II. and Murad V.
Just to mention again the songs fit every aspect of the game, you have calm and beautiful songs for the peaceful periods, traditional songs describing the emotional situation of the Ottoman Population in the Victorian Era connected to all these wars and horrible losses and also war marches if things get serious
Of course I did not only focus on the pure Monarchistic era but also the time where the Youngturks take charge and so there are many songs about WW1.
Aaaaand also there are some songs which are from the time of the Turkish independence war because Turkey can be formed ingame even tho it´s not that many compared to the other songs .
