@BouncealongInf No. They do allow pre-recorded background vocals - and those are built into the song and are playback. In her case, it is her own voice in playback "background". So she is singing over or along with her playback voice. You can clearly hear it when the microphone is taken and you can still hear her voice - it is softer than when she is singing directly into the mic though.
