It is not Fabienne or Petra, I promise...
Here's your answer as to "who sings the new Toyota Prius "Hum" song, "A Prius for everyone." - It is Petra Haden. For more information, please refer to the related link.
SInce no one has answered this, I'm throwing out who I *think* it is: Martina Topley-Bird.
Lenka!
Hum - Stars
I am trying to find this out, too. Some people say it is Kerris Dorsey, but apparently she denies this on her twitter page, so I am still looking... https://twitter.com/kerrisdorsey/status/249968805672017921
If this bird does not hum, then it is not a humming bird but if it sings then it would be a songbird.
Hum - Stars

"You Got to Have Friends. "Later in the movie he did sing and hum "On the Road Again."

Thats EXACTLY who I thought of when I heard it! I was like, that song sounds familiar, pulled up a video from Moneyball and was like, it has to be her! I don't know for sure if it is or not, but it sure sounds like her.
