This is why early on I adopted WMP as my platform. I chose lossless WMA as the format because at the time it was the best free tool out there and WMP could convert files to MP3 when syncing with devices. Also, I always rip every new CD I get before I do anything else with it. That way everything is always in the library all the time. With statistically zero exceptions all of the music info, artist info, writer info, artwork, and other such metadata is preserved. Of the 4,000, or so, CDs in my library, may a dozen or so are missing the extended data, but I manually entered the artist, titles for album and songs, and sometimes the composers into the WMP library at the time of ripping if it didn't find it automatically.
So it is all there in a compatible platform I can use from any of my devices. And no extra work is necessary.
That said, I am really impressed by your effort to achieve near perfection, Haywood.
