Brief description of how to change the music on your login screen. First download the folder in the link and decide which sound track you would like to try out. After making a choice, its time to create a new patch or add into the one you have. Inside the patch, make a folder names "sound", inside of that make a folder named "Music", and inside of that one last folder named "GlueScreenMusic. Take the mp3 from the downloaded folder and place it inside the GlueScreenMusic folder. Rename the mp3 to WotLK_main_title.mp3. When you are finished with that exit out of the patch, delete cache and load up your wow.exe and BAM should be updated music enjoy!
