Jazz singer. No doubt in my mind. So maybe I don't have the voice, but if I were blessed with a good voice, I would definitely become a jazz singer happily!
I think I love jazz because it's got such attitude and emotion in every song- Ella Fitzgerald and Nat King Cole both show that quality incredibly well.
I also love the freedom that jazz singers get to possess. They could rehearse with one version of a song and perform it completely different and still sound amazing. It's the excitement of improvising that gets me- you can be so creative with singing jazz. I love how Michael Buble made this song his own. :) It's so hilarious!
