TIME should be the log(base 2) of the actual time difference, with as many bits of precision as are possible at any given time (if you're messing with unix time_t's, the largest log base 2 will take 4 bits of integer, leaving the other 11 for the fractional part).

<tommyboy> You can get a good look at a T-Bone by sticking your head up a Bull's arse, but most people just take the butcher's word for it. </tommyboy>

So I'll take your word for it...
I mean, it sounds good but I imagine I speak for may users on this board when I say:
"I have no idea what to do with such information."

Perhaps you may have added a few "Custom Shuffle Modes" to your empeg that us "simpletons" might find handy, convenient and usable.

Something like these:

shuffle0=Favorites,PLAYS=-32000
...you'll get a shuffle of your playlist in sequence of number of plays, highest # of plays to lowest # of plays. Keep the player paused and keep reshuffling the playlist and you'll keep getting the exact same sequence of songs.

shuffle0=Favorites,PLAYS=-32000,RANDOM=1
...and you'll get the same as the above, but songs which have the same # of plays will be re-shuffled amongst themselves each time.
