It's made by two songs from the Romeo+Juliet motion picture directed by 'Romeo+Juliet vol 2' di Baz Luhrmann.. here's the titles for both the tracks:

05. 'O Verona (Reprise)' (written by Nellee Hooper, Marius De Vries, Craig Armstrong) 22. 'Death Scene' (written by Nellee Hooper, Marius De Vries, Craig Armstrong)

How come they don't ever play 'Hello' during live shows?

John Lee (Amy's father) posted on EvBoard about this song. Amy wrote the song for the younger sister she lost when she was only 6 years old. She doesn't play it live 'cause it would cause some feelings she couldn't handle during a live show.

I know of a song called 'You'.. how come I can't find the song itself or the lyrics either?

'You' isn't an Evanescence song. It's a personal song to Amy and the band. This means it can't be distributed or downloaded from the web or anywhere else. If you're a fan you shouldn't have it.

Is Angel Of Mine an Evanescence Song?

No. It was never written or played by the band. Here's what Amy said on EvBoard about it:
