Heroes: "We all need to be needed."

Hi everyone. Heroes is totally new to me. I just saw its promotional trailer in other forum today and immediately fell in love with the song that was in Heroes. Does anyone know what song it is? PLEASE LET ME KNOW!!

It starts off like this:

"We're longed to belong. We all need to be needed."

Then the characters start talking and I can't make out anything else.....

Does anyone know? PLEASE HELP!! THANKS!!
By the way, does anyone know the theme song of Heroes? If you know, please tell me, thank you.
