ANyone know how to put 音楽 over a UST? UTAU

from what I found,

"You have to export the sound from the ust file to a wav file
To do this あなた must follow this:
1)Click on the First (P) at the top
2)Click on the thing that says wav-insert japanese here-(G)
3)Get the UTAU audio together with the karaoke with audacity"

other than that I might trying looking on the UTAU wiki link if あなた scroll down to the "Special Features, Guides, Walkthroughs and Troubleshooting" part. Hope this helps and good luck
