If you want all your music, but not the EXACT instruments from the original songs, I would suggest,
vgmusic.com -Video Game Music, obviously.
You can find music for almost, well pretty much all Mario music and other music from other games. A wide variety of systems and games to choose from. Plenty of remixes added also. I would highly recommend that site for all of your music needs.
Hey folks, you should try this. Show people your drivers license and ask them if "they have seen this man."
