ID3 is the problem.
All 6,000-plus of my music is in MP4 format, which is what iTunes uses natively. And, MP4 uses XMP and not ID3.
My only conclusion is that MP4 files can technically play on iXpand, but it just won’t read the tags because it uses XMP. And, it doesn’t appear that iXpand recognizes XMP. I’m a programmer myself, and it isn’t that complicated to recognize XMP. Heck, Windows XP and later even recognizes XMP.
