I recall this recording on LP in the early fifties. It conveys the humour and genius of Mozart with great singers although other than Steber they were not previously identified with WM.
Positive

I have had the charger for more than two years. It charges AA batteries just fine, but has a huge problem securing smaller AAA batteries. To charge the smaller batteries you need to flip down the little button at the positive end. In the beginning one of the four AAA batteries would pop up, and now three out of the four won't hold. The problem is the flip mechanism became loose, and any horizontal pressure would push the buttons back up. What I have to do now is using duct tape and a segment of crayon, apply the crayon on the buttons, and wrap the tape around. You know how painful that is.
Negative

Insert the CD and listen to the first track. This is everything Nightwish is known for. Any fan will love this album
