Well, you get the point. The music is awesome, but there was still a bit more things that would be awesome as well.
And my list goes:
M&L:SS Battle theme
M&L:SS Popple battle theme
Rainbow Road (SMK)
Doopliss battle theme (PM:tTYD obviously.)
Shadow *Peach* battle (Also obviously in PM:tTYD)
I can't think of anything else now, but let's see if you guys can think up anything.
