Wow! On 2 occasion I found myself utterly bewildered on Celine Love's "Good Girl".
On the first occasion... It was the moment where her vocals almost create an atmosphere by virtue of the balmy harmonies we become lost in. She not only uses her voice to punctuate her heartfelt lyrics with her harmonies, but they actually feel like an instrument too. The second seminal moment on "Good Girl" we find towards the end when the key transition occurs. It takes us by complete surprise and introduces new life into the track.
