Oh, I actually explained bad!
Well, the problem:
When I added the music I wanted, the original YR music got available in the TC's with new music (Allies Revenge 2 and Blitzkrieg). So I want to know how to remove the original YR music from the TC's, Thats the problem
If you want more control over the way the music is structured into the game then don't do the music through XCC Mixer - do it manually through the thememd.ini file.
Why? All XCC Mixer has done is make it's own version of the thememd.ini file. Just delete the thememd.ini file in your ra2 folder, extract a clean copy and then edit it as you wish.
