A lot of this music is sad but in a good way, you know? Makes me wanna replay my game again. So much memories, man. No one posts videos about this but the music reuses melodies sometimes, like in "Escape Through the Snow" 21 seconds in you hear the same melody that eventually plays when you have to leave the pokemon world("Farewell " 43 seconds in). There also is normal music that isn't sad like "Stop! Thief!" and one of my favorites is "Friend Area ~ Caves". It also has a lot of ambient sounds like "Rayquaza's Domain" and "Friend Area ~ Cryptic Cave". I do recommend taking a look at these and finding something cool, but some of these are only cool after you've experienced the full game.
