Song sounds like something that could be used for a starting adventure level or near the end of the game where you are given a level to relax on for a bit before continuing on to the end of the game. Very nice song!
The synth sounds a little like a organ to me but with no large reverb or echo applied to keep it as clean and smooth sounding as possible. The drums have a simple feel and I like how fast it sounds at the same time. The other synth sounds nice and I like the up and down feel it gives, can kind of picture someone's mouth but with it being spliced to go up and down in notes.
Overall, very smooth, clean, and fun sounding beat.
