what is the "copy/paste you referring to?" i also don't understand how the audio feature works on ff3usme.

As it was stated previously by Gi Nattak, you cannot import, export, copy, extract, modify or edit a song with FF3usME. You can ONLY assign new BRR instruments, e.g. change the instruments used to play the songs.

By copy/paste, I mean literally copy/paste from a hex editor that has a copy/paste feature (ex: HxD). You locate the song in the ROM, open the hex editor, copy in the clipboard the song data by selecting the data and right-clicking on the mouse and do "copy". You can always use the edit menu to copy and paste like in every program. Then you open your other ROM paste the data. The only thing left is to change the instruments of the song you just replaced. Refer to the music tutorial for that.
