Query: Her voice IS THE KEY IN HERE---SHE HAS IMPROVED A LOT!!

In the previous Cd, her voice sounds kinda DULL and as if that something was missing. Well on this Cd, she really improves VOCALLY. Her voice range is REALLY COOL. And the Lyrics are the BEST TOO. When you listen to the Lyrics, you will just REMINISCE so much from your past and relate to her MUSIC. IT IS A WELL DONE CD.
