Tony, Thanks for the 411. Fortunately for me, my mp3 tags are virtually flawless, though I do occasionally run into one that has a slight error (wrong year, mis-spelling, etc...). I guess I'm really just looking for an easy way to synchronise my hard drive database and my Rio when I find little errors. I either make the changes in both spots, or change them on the hard drive and delete Rio files and re-upload which is cumbersome. Thanks again.
