I got El Cid on my ipod, got no info on it though just took it out the FH files. Plus me and a friend also uploaded some music in the old forums, posted it there. Maybe you downloaded that one. It had no Königsgratzers march in it though.
If you want to take out the music yourself: C:\Program Files\EA GAMES\Battlefield 2\mods\fh2
Go there and then open the .zip file called common_client, I think they where in there. If not try some other files.
