Looking for helps in ripping DS soundtracks

I was trying to rip DS Jump Super Stars and Jump Ultimate Stars soundtracks, because there is no other download link available, and there are some tracks on youtube but just some of them not every single ones.
What I was using is a software called ndssndext. But what I got is like this: 001F.mid – 4shared.com – online file sharing and storage – download – aluo aniki (http://www.4shared.com/music/1KlRDEpl/001F.html?refurl=d1url)
Here is the same soundtrack uploaded by someone else: Lightning City – Jump Ultimate Stars – YouTube (http://www.youtube.com/watch?v=DRqQ9WbhA3c)

I think what I ripped lack of other sound samples. But I don’t know how to fix this.

Please someone tells how to fix this.
