Already covered the mono in my description.
And yes... nobody likes "that guy".
Who Said: once you crack open the 2da you'll see it's fairly straightforward.
Description is the tlk line but unnecessary for custom entries because of the DisplayName column unless you want to go though all the trouble.
Resource is the name of the bmu that will be in your music folder (16 character limit of course)
Stinger1 / Stinger2 / Stinger3 are small wave (.wav) files that cap off combat music when combat ends. These are NOT in your music folder and, if you bother with making them, these would be located in a hak. Because they really are just a post combat end chime, most people don't bother but I did utilize them from the Baldur's Gate, Icewind Dale, and Planescape: Torment combat music on my home server since those stingers already existed.
DisplayName in quotes will be the name displayed when going to select the music within the toolset.
