Demi Lovato is an artist that has been lost for a very long time, actually since her debut she's been stuck in the same type of writing and production. But maybe this time, for real, she's discovering her own sound. She saw too much, lived too much, she experienced trauma heavily, her voice resonates all of that and yet her music used to reflect only her sorrow without TRUE self reflection.
In 'Dancing With The Devil... The Art of Starting Over' her poetic sense blossomed, apart from some generic lyric here and there I can tell she's really evolving, shaping herself to a woman whose expectations she always had.
