Sorry to nitpick, but there are no songs in the Pokemon games AFAIK. Songs are sung by singers.
I'd bring back the main battle theme from Colosseum. So good <3
No need to mention that. I know.
I feel as if I have a duty to iron out the misuse of the word "song." Your apathy simply isn't helping matters. --- Why do I have to move with the crowd of kids that hardly notice I'm around? I work myself to death just to fit in.
