<DIV><FONT face=Arial size=2>How to implement stars ratings, I think, is beyond
the scope of the ID3 specifications. The POPM frame supports the concept
but the implementation inside an application isn't specified.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>By the way, did you know that Microsoft has a
patent on generating weighted playlists based on user ratings. They
patented it in, if I remember correctly, 2005 though many players have done it
for long before then and the idea has existed in the POPM specification for many
years.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Anyway, Microsoft's Windows Media Player has an
option to store their ratings in the file, alternatively, you may want to look
at my metadata backup utility that works with Windows Media Player
libraries. It helps support moving custom attributes when moving on the
same computer or to new computers.</FONT></DIV>

<DIV><BR></DIV>Question:<BR>Why isn't there a "rating" tag under ID3v2? IE
0-5 stars as with many of the players. Sure its implemented in Itunes and
their ipod, but what happens if someone wants to use a different device?
Also moving the music library is a pain because the ratings don't move with the
files. The ratings is how I create many lists, as well as mark songs
for deletion later (1 star). I think this would be well worth 3 bits in
the header. <BR clear=all><BR>-- <BR>life's short, live it </BODY></HTML>
