Any ideas why Amarok drops the scores of songs (which were previously at 100) to 99 after a full listen?  I've got crossfade set to manual change only so I can't see that having any effect.  I have the default scoring algorithm enabled.  Songs range in playcount from 7 to 15 and all drop to 99 so I assume that there is just a very tiny error in the calculation that is lowering the scores.
