So beautiful, I'm in love. It's the perfect background noise music. Other songs to listen to: Robert Schumann's "Traumerei" (I fell in love with this song a couple years ago when I first saw Beyond Borders) and Beethoven's "Moonlight Sonata First Movement."
If you only listen to those three songs you will begin to have an appreciation for some of my favorite music. All these songs, as well as many others, are available here, although the mp3 of Traumerei is played slightly faster than I would like it is still very pretty.
