Today is your lucky day!
I went through a few of the finished MIDIs I've accumulated over the past few years, looped the ones I thought were suitable and uploaded them for the community =p There's a forest theme, a second battle theme, a title screen theme, a kind of mechanical-sounding dungeon theme, and some random theme I couldn't classify but might suit a character or scene well. Enjoy!
