Hey, I was thinking about this feature also.  However, it seems like
it could also be annoying in cases where you want precise control over
the timing of the pause.  In most cases, it would be a nice feature.
This could be resolved by starting playback slightly ahead of the time
that you hit pause:

              time
pre-pause  |---------|...          |
pause      |         |             |
post-pause |      ...|-------------|

|   is the pause
... is fading
--- is playing

This may be far more complicated than necessary...

Also, it might be worth considering a scenario where for some reason
(had the volume up way too loud) you want a fast way to stop the sound
now.  If both pause and stop both have a fade, there would be no good
way to do this in Amarok - you would need to turn off your speakers or
use other master volume level.

It would be nice to figure out a good way to include this feature.
There have been many times where I wished it was available.
