Actually I think that it's the contrary. On 2007-2008 she was like this, shouty and out of tune but since 2009 NEXT LEVEL show she gradually got better with each show that now she got to singing and technical singing stability in both of her voice sound and singing.

Save for TV performances, I don't know why there she doesn't make more effort to sound like in her lives, maybe she barely can't rehearse it and it's hard to monitor her vocals with the music with not many rehearsals before hand or she gets more excited than before and can't control it I don't know but in her shows she still sounds mostly great. INSPIRE in kouhaku was pretty decent. Better than last year's vocal performance. You can see sometimes that she is struggling not to shout and actually sings decently or even great, while not shouting the songs at all (unless if they are her crowd songs and has more original shouty parts or parts she herself decided to shout instead of sing, every time sing sings these lol - Boys & Girls).
