Which zone has the best song?

I find this rather difficult, I love all of the songs and can say Funkiki island, nightmare rift, and paradox green stay at the top of the list. All highlighted the areas and if I listened to the music without seeing the area I could tell the area concept overall strengthening the want to visit all the different worlds.

My final verdict is Paradox greens, I love the tranquility in it mixed with the industrial theme, you can almost hear every Funkey working in harmony. The tad's serene singing, the sounds of ace working with his tools, the futuristic tone of the Rastro, and the mulch's instruments.
