I pretty much agree with Jose
but Ayu's voice can sound quite nice.. like in Memorial Address <3 She has been singing with a deeper voice now and I think most of the times it sounds good. She sounded the worst when she released A Song for XX. I never understood why she had to sing in such a voice because before she released that album her voice sounded quite pleasant o.o
The sound of her music seems to be less original than before.. like with songs such as Real Me, Greatful Days and Ourselves -.- As much as I love Because of You, even that sort of music doesn't sound original...
