Hm... this is kind of neat.
I really like the piano in the beginning and at the end, along with the sound of the pouring rain. Also, at around 1:38 or so, I the style change was pretty cool. :)
The only parts I don't really like were, first off, how quickly everything faded out at 4:16. Second, the switch from styles right in the middle of the song was a little strange, and could've used some more progression between styles. Other than those, it's a neat experimental sounding track!
