bokuga okuru monowa subete katachino nai mono dakedo (konou utaga) kimino kokorono katasumide kagayaku hoshini naritai Sorry, this song's lyrics is very long so, I could'nt send you all at once. I agree this is wonderful song and I try to sing it at karaoke bar in japan. Enjoy!!
It's called "Even Though My Song Has no Form", sung by Hatsune Miku. Basically, a girl had this friend, but he went away. Now, she wants to express her emotions not by material items, but by her voice, which will last forever because it can take no shape (her voice). I hope this helps out.
No... I mean ENE... Her voice has a lot of potential which can really surpass Miku's. I mean it's not overall computer generated, which makes me assume that it's a human singing... I already know Vocaloid 3 years ago... xD!!!
