This all sounds very interesting. I think the clock thing can hopefully 
be worked around (perhaps some form of clock offset correction system 
when you plug your device in - remembering when the clock was last sync 
and using a fairly simple averaging algorithm to update the recorded 
times of played songs?).

I would be very keen on this overall, and would especially like to see 
integrated support for the tag databases format for rockbox in Amarok.

I don't think the battery drain of writing the stats would be too great 
and it is probably easy enough to keep a limited number in memory and 
only write it to disk when it is spinning already.

I've nto really got time to help on this just now but perhaps towards 
the middle/end of summer I'll be able to help out.
