Love the F210, but the MP3 player didn't recognize album or artist for most of the songs that I brought over from Lisa's iTunes.
After some research, mp3tag seemed the best option and least likely to contain malware. This forum thread seems to go over lots of different types of mp3 tag problems and their solutions: http://social.technet.microsoft.com/Forums/en/w7itpromedia/thread/0b284232-aaf4-4cd8-8fee-91b46e9acbd9
And here's where mp3tag comes from: http://www.mp3tag.de/en/
The most likely culprit seemed to be which ID3 tag format was being used (particularly since some files worked and some didn't. There is apparently an ID3v1 and an ID3v2, files can have either or both, and they're different enough from each other to be incompatible for some players.
Here's a different product that had changing the tag version built into its front panel: http://www.maniactools.com/soft/mp3tag/copy-id3v1-to-id3v2-or-id3v2-to-id3v1.shtml
Here's how to do it in mp3tag. The key is to set the tag save type in Options, then save the tags. In practice, it is often necessary to fiddle with the tags before they will be saved. Also, the default settings for the files on my little micro-SD card seems to have been "Read Only", so saving may not have been having an effect at first (although I didn't get any feedback saying that there was a problem). http://forums.mp3tag.de/lofiversion/index.php/t6727.html
So, it turns out that the version that I needed was version 2.3! There's also a version 2.4 and maybe other later ones. The plain version 2 or maybe it's version 2.2 could not be read by the F210. Most of the tags in Lisa's iTunes were 2.2, and many were noted by mp3tag as "Bad 2.2". There are also apparently three different flavors of 2.3, UTF-8, UTF-16, and ISO something. The player didn't seem to care between UTF-16 and ISO.
This forum thread had the 2.3 answer, but it was buried under a bunch of distracting stuff about FLAC version tags: http://androidforums.com/samsung-captivate/139592-samsung-player-doesnt-recognize-my-music-tags.html
This is just an interesting forum thread by a guy who tried a bunch of stuff to fix a problem only slightly related to mine: http://forums.mp3tag.de/lofiversion/index.php/t12455.html
