There are some Macross songs that are in the game but not in the Premium Sound edition, meaning they only exist as instrumental arrangements, and now we can no longer do universal BGM replacements. Fuck, that's going to bug me so much when I reach a Macross stage and they play those songs as a story event but there's no vocals. I remember when V came out on PC there was a way to mod replacement music into the game before they officially updated it with custom BGM settings, I wonder if that still works...
