Their Planet Nice.
I have to say, I really do like this piece.
What I find most interesting about it is that while still being a spacy and almost adventurous sounding piece, it also combines that of a kind of RPG like town theme. It ends up very much like that of the music of a stage of Mario Galaxy. If anything it certainly gives off a planetary feel.
Though it some places it does seem like too many instruments are going at once. It doesn't detract much from the piece as a whole, but is noticeable.
