I barely see anyone mentioning the Golden Sun's soundtrack when talking about the game, or when talking about RPG soundtracks, or even in best GBA music lists.
While most of the music in the game is cheery, to me the best tracks are actually the amazingly sad ones. This game has a disproportional amount of town music that while great, are really sad and depressing. Just listen to these and tell me you don't feel some kind of despair.

Then there's the Cave Theme, it sounds like there's a funeral procession happening inside them.

These tracks reminds me a lot of the Illusion of Gaia soundtrack, both in the style and instrumentation. It's like the music wants to be hopeful, but they have this underlying feeling of despair and sadness. Just like the Gaia soundtrack.
As for some awesome tracks that are not depressing? There's the Sol Sanctum theme - it fucking rocks!

And the Venus Lighthouse theme:

I've only really played the first Golden Sun, still have yet to play The Lost Age or Dark Dawn. What are some good music tracks from the sequels?
