Hahahaha, yeah, Lacus's singing voice was funny, it seemed like an older person was singing it, and it was off-tune too. But I guess they translated the song pretty good. Also, another plus at dubs, is because companies get seiyuus that are professional, and can sing if the character needs too, while dubs could care less about that.
Nelvana had one priority: to make CCS into the new pokemon, if a anime contains something about catching stuff, it means thats all it will be about, that's why all the romance/humor and pratically everything else was taken out. There is more to a show than catching stuff ya know.
