In this tutorial im going to help you change your Intro Music in World of Warcraft 3.3.5
Go to your Wow Directory
Go into "Data", Create a new folder called "Sound" then Create another one called "Music" Then one more called "GlueScreenMusic"
Now it should look like "\Data\Sound\Music\GlueScreenMusic"
In the folder GlueScreenMusic Instert your media file (Mp3) mine is called "CnWTYqwm5C5C.128.mp3" (Wolf at the Gates 3 SoundTracks - By Jason Hayes.)
Now it should look like "Data\Sound\Music\GlueScreenMusic\CnWTYqwm5C5C.128 .mp3"
Rename the Mp3 mine is called "CnWTYqwm5C5C.128.mp3" so i should now change it to "Wotlk_Main_title"
Now it should look like "Data\Sound\Music\GlueScreenMusic\Wotlk_Main_title .mp3"
And now when you start up Wow.exe The mp3 you inserted should be playing.
