What's the song on the "Parenthood" commercial?

Search: "i'm just a little bit caught in the middle"

Why: I just saw that trailer. I think it was on another commercial a while ago.

Answer: "The Show" by Australian singer Lenka!

Source: Metro Lyrics

The More You Know: It was also in an Old Navy commercial! The lyrics go:

I'm just a little bit caught in the middle
Life is a maze and love is a riddle
I don't know where to go, can't do it alone
I've tried and I don't know why

I'm just a little girl lost in the moment
I'm so scared but I don't show it
I can't figure it out, it's bringing me down
I know I've got to let it go and just enjoy the show
