It seems like the Super Mario World game over music is meant to sound like that. In a personal standpoint, it sounds sad. But also tells you to "chin up" and tells you good luck next time type of vibes.
3:04 idk if it's just me but something about the Sunshine one used ti really stress me out. The fact that it's the same as the regular death one but then quickly transitions into the big death one made it to where I was always stressed that it was my last life and I didn't realize it.
0:21 My favorite death sound. During my childhood in the late 80s & early 90s, I said that death sound sounds like Mario is saying "LOOK AT THIS...AT AT A DO UM A DO UM ADOOM". 😂
