I must, the title fits the song very well.
This reminds of Bayou Boogie from Donkey Kong Country 2. Definitely look if up sometime. To borrow your own words, it has a "muggy, humid" sorta sound. I like this, it's very simply, but nice. Definitely good background music. I guess my only complaint is that it is very repetitive. Not really a bad thing for this type of song I suppose, but whatevv, I like it regardless!
So in short, it doesn't do TOO much, but what's there is nice. Well-done :-)
