Firstly, a couple of weeks ago I was listening to "What I Am" and I started to feel really emotional. I don't even know why. Is that weird?
Anyway, I have to say, I enjoy What I Am better as a song. It seems to have a lot more energy on the performers part (except for Will I.Am, that is), and it's just catchier to me. However, Bruno Mars' vocals are far better, so the song gets some points for that.
Also, does the song remind anyone else of the Smarter, Stronger, Kinder song?
