Looking for sheet music?

I bought this cd from Target, you know one of those displays in the candle isle. The one on the wall with the different clips of music you can push to listen to. I bought a cd from there and with out thinking threw the cover away. I really like the music and want to get the sheet music so I can learn to play it on the piano. I have looked and looked, and I can not find it anywhere. The name of the cd is Reflections of Nature. It has beautiful pieces with piano, and cello. It also has birds chirping in the back ground. Does anyone know where I can get that? I have looked on-line and throughout music stores I can't seem to find it!!!
