Found this great
video (~7.2 MB WMV file). Just click the link and it will send you to a page where you can right-click and hit "save target as" to save it.
Don't really want to describe it as it kinda gives it away, just that it is Nintendo Music
And if anyone could help me place what songs are from what games, I'd appriciate it (I know most, but not all of them).
