鳥の詩 (Tori no Uta)

Not the opening from air! This is a japanese oldie. If you have not listen to japanese oldie before, this will be a good example. 杉田かおる( Kaoru Sugita ), an one hit wonder, who is also an actress performed this wonderful song which was remixed and rereleased as a three tracks single few years ago. In my opinion, nothing is better than the original:)

Since its trial version, please delete after listening. The quality is bad anyway. Get your original copy if you like it.
