WoWMusicPlayer plays your music inside thw WoW client. However, since file accesing is forbidden from inside the client, this addons provides an external tool to create your play list.
The easiest way is just running "WoWMusicPlayer.exe" inside the addons folder. Add the single files or folder you want, and click "Generate play list".
However, if you don't like using external tools you can edit by your own -and under your own risk- by going to the SavedVariables path:
..\World of Warcraft\WTF\Account\YOUR_ACCOUNT_NAME\SavedVariables\
and opening the file "WoWMuscPlayer.lua" -it will be created after the first login/logout.
A sample would be:
MPSongList = {
"song_1.mp3", [1]
"song_2.mp3", [2]
"Song_3.mp3", [3]
}
Notice that all the files that are being played MUST be inside the directory
..\World of Warcraft\Interface\AddOns\WoWMusicPlayer\PUT_YOUR_MUSIC_HERE\
