Which homebrew games have iconic music?

I'm considering developing a rhythm game for NES. But I won't be able to write all the music myself, nor do I suspect that publishers of popular music would be willing to work with a retro micro-ISV on reasonable terms. Which homebrew games (for NES or any other retro platform) have iconic music?

I don't know how to answer your question directly, butI've got piles of semi-finished and finished Famitracker music that I'd be happy to let you use.

A few spring to mind where I still remember the music:
* Utaco
* Lizard
* The Tao of 007
* Super Bat Puncher

Don't know if they are considered iconic, but Alter Ego and Lan Master are one of my favourites.

I also like
-Streemerz
-Legends of Owlia
-Battle Kid 1 + 2

Neotoxin has some really nice, melodic tracks.

I was going to suggest Popcorn, but now that I think about it... I don't even think the creators of Pengo obtained the rights to use the music.

Have you considered Korobeiniki or Kalinka? I know, I know. Typical

Not in any homebrew games, but these are strict 2a03 NSFs that I found exceptional:

8bit to the Moon (Nurv Cockyman)
King Chippo (Robert Kreese)
King of Hearts (Juan Linietsky)
Stress (RushJet1)
Wayfarer (Warlord)

I think these are all originals. If any of these aren't, let me know.

You'd definitely want to include your remix of the Mouser theme.

Same. Depending on what you're looking for I can potentially adapt the NES parts of a Marshall Art song or two to fit your needs.
