She'll probably add a few more tracks in gradually. I'm sure if she does Baby I or another upbeat track, she's going to want her dancers on stage with some new choreography & some visuals to go along with it so that's going to take a little bit of time.
I would like her to add Piano since that's a fan favorite & she performs it live well. I saw her in on The Listening Sessions tour last year & that was standout.
