What is the name of the last song on Season 6, Episode 02? Who sings it? Is it on a CD?

Lyrics:

I never really knew when the 天使 sighed
Never knew exactly what I’d find
Looking down the road of another life
Looking down the road of another life
I don’t know what’s left inside our life
No don’t walk away, tell me all the steps I need to take,
No, no one ever really knows,
No one ever learns to live alone
They just get tired and the hearts get cold
Never really knew just what I’d find
Looking down the road from another life
