I make music, and every once in a while I love to make short theme songs/mood piece demos. I've uploaded stuff to soundcloud but they'er not really full songs made for digestion yknow? So where as game devs, do you guys usually look for stuff like this? Making music for games has always been a bucket list dream of mine !

I’d try freesound.org.

You can post your music/game assets right here on itch - we have a category for game assets or more specifically a tag for music.

Sound Ideas offers royalty-free music for use in games, but you have to file a cue sheet if you decide to commercially distribute your game.
