I finally found out how to rip music from NDS roms so I decided to rip music from this game because I like the music and I'm pretty sure some other people wanted the music from the game as well.Anyways all the Mario music from the game is in this zip file.Only two Mario songs are missing,the over world theme is not in the zip because when I was ripping it from the rom I listened to it and it seems it's missing an instrument and I didn't rip the underground them because it sounds exactly as it was in mario bros for NES...so I just put the character select song in the zip to make up for it.

The songs only looped once so I edited the songs so they loop twice.
Enjoy!
