I am quite disappointed. I purchased this accompaniment CD, on the basis of the short clip provided online, because the clip was within my comfortable vocal range. To my dismay, upon playing the entire CD, there are **three** key changes in the second half of the song, placing the remainder of the song seriously out of my range. I am now stuck with an accompaniment CD I cannot use. This type of major key change situation should somehow be noted for online buyers' benefit.
