In the Sunlight is neat because it's basically just pan pipes from three different soundfonts layered on top of each other. One from PMD Sky, one from M&L Bowser's Inside Story, and the newest one from Spectrobes: Beyond the Portals. The last one has a certain richness to it that I think In the Sunlight needed.

Not enough of an update to make me want to redo the Soundcloud upload from scratch though, since replacing audio requires premium.
