I think it's lovely. Reminds me almost of a syncopated Pachelbel's Canon in D. I can see why your 3 year old would like it, but it's nice for children of all ages!

I think the lossy format is more telling when you get into orchestral genres, and the .mp3 probably doesn't do this justice. I also wonder if the strings might stand out more fluidly if you used a virtual symphony such as VSL, Kirk Hunter, or Garritan's GPO.

Thanks for posting. Very sweet.
