You know, the type of music that plays during factory stages. It's usually of the techno/industrial type, and Kirby 64's Factory Inspection typifies this style. Repetitive anvil clashes and a wide variety of mechanical sounds are used well to provide the tracks with the atmospheric component they need to represent the stage well.

So, am I the only one that enjoys this type of music in games or are there others?

Oh yeah, I like these, too. Be sure to check out my VGM albums in a few days, because I will make one based on that theme, it'll be called "Power of Science".

A few of them:
Secret of Mana - Leave Time for Love
Mario Basketball 3on3 - Wario Factory
Sonic the Hedgehog 2 - Chemical Plant Zone
Sonic Riders - Egg Factory
Lost Vikings 2 - The Future
Transsibiria - Taymyr Industries (I'm having that exclusively... the composer gave it to me 8D)
Super Mario RPG - Weapon Factory
Terranigma - Genius' Playground
Final Fantasy VI - Devil's Lab
Donkey Kong Country 2 - Mine

Donkey Kong Country Had the best factory theme.

Drill Dozer has this kind of vibe all over its OST.

The closest thing I can think of is:

Mecha-Robo Corps Charge! - Blue Dragon

Stuff that has the same feel:

Slam Shuffle - Final Fantasy VI
Robo's Theme - Chrono Trigger
Parasite Queen Battle - Metroid Prime
Lifeline - Breath of Fire V

The only one I can think of is Theme of Madril from Okage: Shadow King.
