Track composed by Aaron Krogh
There's another track I found quite memorable in Quest of Dungeons and it's the jovial music you here while perusing the merchant's wares. Some of the music you'll hear on this soundtrack is offered for free by composer Aaron Krogh for use in RPGMaker projects, which is pretty amazing if you ask me!
As mentioned, the track has a jovial, light-hearted nature to it that is a bit of a reprieve from the other music you hear in the game while dungeon crawling.
