Know of any awesome unused tracks from video games?

I've got quite a selection from Final Fantasy 2 NES.

I'd love to see what types of other music developers have hid from our ears.

If it's unused tracks you want, try this one on for size! It's from Wario Land: Shake-it!

For unused tracks, there's a few of them that I know of. There's probably the most well-known, simply named "Advent" from Banjo-Kazooie...
The other most well-known one being Hidden Palace Zone this song from Sonic the Hedgehog 2.
Then there's also this tune that is hidden in the PC version of Sonic & Knuckles.
3D Dot Game Heroes had a second boss theme they never ended up using.
Mega Man V for the Game Boy had a handful of unused or alternate songs, this one is an example.
And technically I'm counting this as unused since DuckTales Remastered snuck it into its files but never used it, but Transylvania had a completely different song in the prototype versions of the game.
And Jazz Jackrabbit 2 had not one, but two remixes of the original's bonus stage that never ended up being used.

This isn't quite unused so much as it is impossible to hear under normal circumstances (being that the player usually lands on the Frog Switch right away, thus being stuck with the count-down music for this level), but Wario Land 4 has a unique track for the Golden Passage level.
