Hope it's okay to post here, the tutorial sections seem dedicated specifically to WoD and WotLK, but I'm playing on a vanilla client.
I'm specifically wondering how to add music to the game, not simply replace it. I found Leeviathan's re-score mod that adds a ton of Cata music to the game and it got me wondering about making one for more in line with my own preferences. I got Ladik's MPQ editor to open MPQs, but I'm not sure if/what I need to edit in addition to just dropping new tracks into the MPQ. I noticed the re-score mod (from Leeviathan's merged mods) doesn't seem to follow the original file structure.
Could somebody point me to a tutorial or something specifically outlining how to add additional music via a patch?
