Whenever I listen to this song, I picture some cute little creatures scurrying around! It’s a great simple piece, nice combination of two uncommon instruments! Tiersen working his magic as usual! 
So here’s my go at it, with some Totoro’s coming along to help! 
Dear Yann Tiersen,
my name is Marisa and I’m a childrenswear designer from Thailand. I about to lunch my website and my first collection for spring/summer 2011. I have watched the movie Amelie and fell in love with the song. With this writing i want to ask for your permission to use this song on my website, if that is possible.
I would really appreciate it:)
Thank you very much
Kind regards,
Marisa
