Favorite video game music tracks?

I just fell in love with this track after 8-bit music theory covered it.  Zelda - Majora's Mask - Astral Observatory:

Sim City 4 - Wheels of Progress:

All of this music is copyright free, and was for a scrapped RPG game. @PeterthePapercomPoser I think you might like "Cerulean forest" from 3:25 to to 5:06 

The new ninja gaiden game's music is some of the best game music I've heard since the 2000s.

Found this track from Gundam Wing Endless Duel - Port in a Super Mario World rom hack race level!

Found this in a SMW rom hack race level with the help of some kind YouTuber commenters!  Beyond the Hill - Kirby Return to Dreamland:

This popped up in my sidebar. I'm 5 years late to this conversation, but I have to add in an OST I don't think is being mentioned in this thread (as far as I've read anyhow). 

ALL time favorite video game OST has to be, hands down, The Halo Trilogy (+ODST and Reach OSTs) Soundtracks. Or rather, the original Bungie soundtracks composed by Martin O'Donnell and Michael Salvatori. One of their tracks also featured Steve Vai (😎) which is too epic to ignore. 

Here's a couple of my favorite tracks throughout the years of my childhood playing Halo and now in my adulthood, can much better appreciate the artistic work that went behind these, in their totality. 

(I have a transcription feat. Halo: Reach tracks, in my pocket that I don't think I've shared here that I will share soon 🙂 This is the first track in that Medley) 
 

This one has always struck a chord in my heart. It's the piece you hear at the end of Halo 3: the end of the trilogy. We all thought this would be the last game in the Bungie saga. So for the credits to roll with this piece being the sound that walked us into that slow fade to black, is nostalgic as all h3ll 😞 
 

Here's probably one of my all time favorite tracks from O'Donnell and Salvatori. Just allowing that backing track to take you on a journey, with the subtle sound of Rain, and the amount of space given for the sounds from the Piano & Saxophone to just resonate in your memory for a bit, was just genius. 

Just a few examples... Much much more work in those games that just strike a chord. 

An Honorable mention, from the 343 Industries team when they took over for Halo 4 and beyond, would be the Halo 4 track;

Kazuma Jinnouchi did very very well to pay homage to O'Donnell and Salvatori here. Really allowed me to respect what the Composers did for this game's track, well. I was afraid I wouldn't like this title entry. But the music saved it for sure, in my eyes.
