Hmm... That would be a great idea!!! Something to get the information from the database and update the associated file.
This is actually very simple, if it does not have to be very elegant. Use sample command-line ID3 tagger that comes with id3lib distro, and call it with appropriate options from a short Perl (or whatever) script that parses *1 file to update tags in the corresponding *0 file (*1 files are not database per se, but contain all the information database is constructed from). Granted, I am not sure whether id3lib with utils is available in binary ARM form. If not, some compiling is in order... (or one can do the whole thing on a PC, after ftp-ing the whole /drive0 and /drive1 over.) Nice excercise, anyway
I would have tried this this weekend, but my only home machine (an ancient laptop) has just died on me

Oh, well...
