Soundtrack allows you to assign your own music to almost any event in the game.


Installation
Soundtrack requires extra installation steps to gather your music information, so please follow these steps:

Download and Install: Curse Client or manual install, Soundtrack must be extracted in World of Warcraft/Interface/Addons.
Move the SoundtrackMusic folder: Manually copy the SoundtrackMusic folder and its contents, located in Soundtrack, to Interface/Addons.
Get some MP3s (or Oggs): You can copy your mp3s to Interface\Addons\SoundtrackMusic. You can put your mp3s into subdirectories or subfolders for organization. If you can run GenerateMyLibraryWindows, go to Options > Add mp3 file or Add folder and select what you want. GenerateMyLibraryWindows has Junctions turned on by default (see junctions in FAQ below). This will create a junction to the folder you select (similar to making a shortcut to a folder).
Generate your library: You have two choices here: Install Python, a programming language, and run GenerateMyLibrary.py. Or run GenerateMyLibraryWindows.jar and go to Options > Generate My Library. This will create MyTracks.lua inside of the SoundtrackMusic folder that you copied earlier.
Play World of Warcraft: Start up World of Warcraft. When you go to the character screen, open up the Addons and check that both Soundtrack and Soundtrack Music are checked. If your tracks do not show up in game, more than likely Soundtrack Music is not on.
