I would very much like the song that plays in the second half of this video:

The song starts around: 2:00

Very old thread, but if anyone is watching this or still looking for it, the song is on youtube here:

Iris~Shiawase no Hako - YouTube (http://www.youtube.com/watch?v=O907meeK0Fk)

Just enter that link into a site like:

YouTube to mp3 Converter (http://www.youtube-mp3.org/)

or something like it to get an ok quality version. :)
