Where can I get the song they play in Seibu Supermarkets in Tokyo, Japan? -

I lived in Japan for 7 months, and I used to love the song they played on loop in the supermarkets near my home. It was sung by a large group of kids, and it was really catchy. Anyone know which one I mean??

I ve never heard, but is this it? http://www.seiyu.co.jp/eco/smile.shtml (If you scroll down, you can listen to music) The title is quot;Smilequot; Seems like singing about ecology...
