Re: The singing, the main thing I'm thinking is it's kind of a bridge between the two cultures of the Anthro people and the Human people, in a kind of nice way. A common bond of a sort, and something they both share, since there's going to be some hints that they have some kind of common history and origin somewhere along the line, and that mentally and emotionally, they have a lot of similarities as well. So, it sort of ends up building a bridge between them. It's certainly not going to be a SECRET WEAPON AGAINST THE ALIENS, and it's [i]definitely, absolutely and utterly[/i] not going to be LISTEN TO MY SONG, since the main character in Macross 7 is one of the most irritating characters in fiction I've ever come across.
