It's that soothing alto. Anita Baker actually helped to orchestrate the beginnings of Toni Braxton's solo career. When she was pregnant and not recording, L.A. Reid and Babyface needed a singer to record a demo of a song they'd written for Baker for the Boomerang soundtrack. Baker suggested Braxton, and the song, well, that was "Love Shoulda Brought You Home." Braxton's version placed on the soundtrack and became her official breakthrough.
