I was thinking about the TLEN field which is part of the ID3v2 standard… does the Xing encoder add something different, and do you care about the TLEN field at all if you mention a Xing one instead?
Wrong thread, I think. 🙂
But no, I read both. But there are a *lot* of mp3s with xing tag but no tlen. I’ve supported tlen since before 0.2.4, so if iTunes gets the length right and I don’t, it’s because it’s an old file (or old tagger) with xing but not tlen.
That’s my guess anyway.
