I tried it on PId 669 compatible body pattern ID is 191,80 ( so it could be worn by both male female avatar)
on mesh column change opacity texture to black apply changes.
Go to action tab
Name the trigger (sample mix0)
Add your ogg file...apply changes....
do this to all your ogg files for this song
for the next song...name the trigger (sample jazz0)
Add your ogg file...apply changes....
