[ID3 Dev] Apple iTunes complicance issues

Hello Ernie.  I'm sure most of the members of this list would greatly appreciate any help you could give with resolving the iTunes ID3 compliance issues.  As you can see from the other responses, there are some fairly big problems with the way iTunes implements the ID3 standards.

I have a quick follow-up question.  What is your criteria for "real-world interoperability consequences"?  I think that by definition ID3 developers are a nitpicky lot, so I'm not asking about highly esoteric issues in rarely used frames.  But it seems to me that problems like the ID3v2.4 non-syncsafe size issue and iTunes inexplicable preference for a deprecated ID3 version (ID3 v2.2) would cause interoperability consequences that would warrant attention from Apple.

Again, thanks for your reply.  I hope that the list has found resource that can help address these problems from within.

  Have you filed a bug? 


  If you can file a specific bug explaining the concrete, real-world interoperability consequences, I can help escalate it to the iTunes team.

    Apple iTunes suffers from the same problem as Windows Media Player 11 when it comes to ID3V2.2 TYE and ID3V2.3 TYER frames.  In both tag versions iTunes adds a leading and trailing zero byte to the frame.

    And, of course, there’s the issue of iTunes defaulting to the obsolete ID3V2.2 tag in the first place.
